Q1: NATS 1880 Project 3 Due: Monday, April 8, 2024 at 11:59 pm Please submit electronically via eClass Student name: Yusra Rostom Student number: 218647735 1 Project Description For nearly 20 years, astronomers have been monitoring the brightness of distant stars in an attempt to determine whether or not any of them host a planetary system. A measure of a star's brightness as a function of time is known as a light curve. Periodic fluctuations within a star's light curve are an indication that planetary transits may be occurring, where a planet is periodically passing between Earth and the distant star causing a temporary decrease in its brightness (although fluctuations can be caused by other astrophysical phenomena as well!). Over 3000 confirmed exoplanets have been detected via this Transit Method, mostly due to the Kepler Space Satellite and the Transit Exoplanet Survey Satellite. In Project 3, you will be provided with a simulated light curve that is comparable to those studied by astronomers today. Through an analysis of this light curve, you will determine whether or not your target star has any planets orbiting around it and what some of their properties are. You will also be asked to infer what other properties the planet(s) may have and evaluate its habitability. Both course materials and independent sources will have to be consulted in order to complete this project. Be sure to cite any sources used in your analysis. 2 Data The target star that was studied by your fictitious telescope has a mass, luminosity, radius, and temperature of 0.30 Mo, 0.008 Lo, 0.31 AU and 3157.18K. To access the observational data, go to link posted on eClass and find the .csv file named after your student number. A small portion of the data is illustrated in Figure 1. If you don't have experience with comma separated values (csv) files, note that they can be opened with Microsoft Excel. However you may use any software program that you wish (e.g. Google Sheets, TOPCAT). Each file contains measurements of the star's light curve, with the first two columns marking the time of a brightness measurement (in years) and the relative brightness. For this project, we will ignore measurement uncertainties that typically come with this type of 1 Relative Brigthness 1.000 0.999 0.998 0.997 0.996 0.00 0.02 0.04 0.06 0.10 0.12 0.14 0.08 Time (Years) Figure 1: Portion of your simulated light curve, which is a plot of relative brightness versus time (in years). 2 data. I highly recommend first trying to reproduce Figure 1 to make sure you are handling the data correctly, however a reproduction of Figure 1 is not necessary for your report. 3 Analysis Your report should begin with an Abstract (maximum 250 words) that summarizes your findings and an Introduction (maximum 500 words) that outlines our motivation for finding exoplanets and how the transit method works. The rest of your report should be followed by sections titled Results, Analysis, and Bibliography, which have no word limits. For your analysis, make a plot of the entire light curve and then create a zoomed-in graph of one transit for each confirmed exoplanet. Note that, just like real observations, there are some times when it was not possible to observe the target star. So be sure to choose a well resolved transit to plot as your zoomed-in image. Also be sure the axis are properly labelled and the axis range is appropriate to view the transit event such that the detailed shape of the transit can be seen. Your submitted report should contain a section with all the necessary figures in the Results section. From these figures, answer the following questions and include them in the Analysis section of your report. a) How many exoplanets are you able to confirm are orbiting your target star? How do you know? [2 marks, approx. 25-100 words] b) How many unconfirmed exoplanets do you have orbiting your target star? How do you know and why are they unconfirmed? [2 marks, approx. 25-100 words] c) For the confirmed exoplanets that you have discovered, what are their orbital periods and size (e.g. radius)? Put the data in a table and explicitly show your calculations below the table for one exoplanet. [4 marks] d) What properties of the confirmed exoplanets can you derive from the information given, other than their orbital periods and radii? Put the data in a table and explicitly show your calculations below the table for one exoplanet. [4 marks] e) What can you say about the habitability of this planet to life-like-us based on the evidence alone? [2 marks, approx. 25-100 words] f) Would your analysis of any exoplanets that you deemed habitable in the previous question change if, through transit spectroscopy, you learn the exoplanet has a 90.00atm atmosphere that is 96.00% carbon dioxide? Explain your reasoning [2 marks, approx. 25-100 words] 3 g) How confident are you in your conclusion about each planet's habitability? What informa- tion would you need to increase your confidence. Be specific! [2 marks, approx. 25-100 words] Finally, end your report with a Bibliography section if you used any additional sources. You should also have in-line citations throughout the report wherever the information was used. + 4 Additional Notes • Due to the uniqueness of each dataset, it is entirely possible that you have been provided a simulated light curve is difficult to analyse. So please note that all light curves are meant to have a minimum of 1 exoplanet (if not more). If you feel like your data contains an error and has no confirmed exoplanets, please contact nats1880@yorku.ca or stop by my virtual office hours. • You are all encouraged to discuss the project amongst yourselves, but the submitted work must be done by you and you alone. Directly collaborating on another student's analysis is an academic offense. • In addition to the posting questions on eClass and providing help after class or during office hours, there will be a dedicated Project 3 help session on March 21 instead of a lecture. 5See Answer

Begin by familiarizing yourself with the capabilities of the Hertzsprung-Russell Diagram Explorer through experimentation. An actual HR Diagram is provided in the upper right panel with an active location indicated by a red x. This active location can be dragged around the diagram. The options panel allows you to control the variables plotted on the x-axis: (temperature, B-V, or spectral type) and those plotted on the y-axis (luminosity or absolute magnitude). One can also show the main sequence, luminosity classes, isoradius lines, or the instability strip. The Plotted Stars panel allows you to add various groups of stars to the diagram. The Cursor Properties panel has sliders for the temperature and luminosity of the active location on the HR Diagram. These can control the values of the active location or move in response to the active location begin dragged. The temperature and luminosity (in solar units) are used to solve for the radius of a star at the active location. The Size Comparison panel in the upper left illustrates the star corresponding to the active location on the HR Diagram. Note that the size of the sun remains constant. Exercises Drag the active location around on the HR Diagram. Note the resulting changes in the temperature and luminosity sliders.

Q18:Problem 1. (15 points) Ptolemy vs Copernicus (1) In this problem and the next we will compare how Ptolemy and Copernicus handled the inner (or inferior) and outer (or superior) planets in their respective models of the Solar System. To keep things simple, we will neglect the planets' eccentricities for the purposes of these two problems. (a) As we discussed in class, in Ptolemy's geocentric model of the Solar System the centers of the epicycles for the inferior planets Mercury and Venus are tied to the motion of the Sun, in order to keep these two planets from 'wandering' too far away from the Sun in the sky. The maximum elongations (i.e., angular distance from the Sun) observed for Mercury and Venus are max 22.8° and 46.3°, respectively. Demonstrate that, in the Ptolemaic model, 0 max can be used to estimate the ratio of the radius of the epicycle, E for each planet to that of its deferent, D, but not their absolute values nor their ratios to the Earth-Sun distance. = (b) In the Copernican model, on the other hand, show that the orbital radius of an inferior planet is given by r = R sin max, where R is the Earth's orbital radius, or 1 Astronomical Unit (AU). Use the values of max given above to evaluate r for Mercury and Venus. Give your answers to 3 decimal places. (c) With the help of a diagram, calculate the minimum and maximum distances from the Earth for an inferior planet in the Ptolemaic model in terms of D and the parameter (max. (d) Do the same for the Copernican model, giving your results in terms of R and max. Show that the ratio of minimum to maximum distance is the same for both models. (Do this analytically, rather than numerically.) In this sense, the two models are equivalent, but Copernicus considered the inability to relate the orbital radii of Mercury & Venus to that of the Earth to be a major failing of the old model. Do you agree?See Answer
Q19:(a) The Greek astronomer Aristarchus, in the 3rd century BCE, is thought to have been the first person to have deduced the distance from the Earth to the Moon, using observations of lunar eclipses. Aristarchus first observed that the diameter of the Moon was approximately one-third of the diameter of the Earth's shadow, at the distance of the Moon. He also knew that the angular diameters of the Moon and Sun, as seen from the Earth, are almost exactly equal, based on observations of solar eclipses. With the aid of a sketch of the geometry of a lunar eclipse, show that these two observations imply that the physical diameter of the Moon is approximately one-quarter of the diameter of the Earth. (b) Now using the fact that the angular diameter of the Moon is close to 0.5°, or a little under 0.01 radians, estimate the distance of the Moon in units of the Earth's diameter ᎠᏯ . (c) About 19 centuries later, the Italian-French astronomer Giovanni Domenico Cassini attempted to estimate the distance to the Sun by combining observations of the planet Mars when it was closest to the Earth, against the background of distant stars, from two widely-separated places on Earth. (He used data from Paris and French Guyana in South America, having sent out an expedition for this purpose.) From these data he calculated that the difference in the direction to Mars would have been approximately 40 arcseconds, if it had been possible to observe it from the Earth's North and South poles simultaneously. [Recall that there are 3600" in 1°, or 206, 265" in one radian.] Assuming that the distance to Mars at the time was 0.5 AU, use this result to estimate the distance to the Sun (i.e., 1 AU) in terms of the Earth's diameter De. In fact, both of these estimates were quite accurate, for their times, and each became the standard value used by later astronomers for a century or more. Nowadays, we know the distance to the Moon accurate to a few centimeters, thanks to laser retro-reflectors left on its surface by the Apollo missions. The AU was not measured accurately until the advent of radar astronomy and interplanetary spacecraft in the 1960s, though many more attempts were made in the interim, mostly using transits of Venus to gauge the diameter of the Sun.See Answer
