PLEASE ANSWER QUESTIONS FROM SECTION C ONLY. The graphs below (figure 1 2 3) are posted as well as other important information.

LEARNING OUTCOMES: 1. To understand how we detect exoplanets 2. To learn how we can extract information about exoplanets from light curves Introduction In this project, you will make use of tools and techniques that astronomers use to view, analyze, and interpret light curve data about exoplanets. You will make use of topics and skills learned in-class, and apply them in new scenarios, and create new scenarios of your own. Materials and Tools . Your assigned light curve/figures (see instructions below) . The Exoplanet Simulator Kepler's 3rd Law Calculator . Calculator.net . Paper/pen/pencil and/or tablet Instructions PRELIMINARY SET-UP AND WORK 1. Find your assigned light curve. Each student has been assigned a randomly generated light curve. To find yours, go to the Project 4 - Investigating Exoplanets section of the course's eClass site, and find the link to the PDF entitled Student Light Curves. Click that link and search for your student number. Your student number will be at the top of the page that contains all the information you need to complete this project. It contains: Top information: data specific to your target star Figure 1 - Light Curve - this plot shows many transits of suspected exoplanets around a target star Figure 2 - A zoom in on one of the transits (you can tell which by the depth) Figure 3 - A zoom in on the other transit (you can tell which by the depth 2. Investigate The Exoplanet Simulator found in the Materials and Tools section above (and in Section 21.4 Planets beyond the Solar System: Search and Discovery of our textbook Astronomy 2e). 1 of 5WRITING YOUR ASSIGNMENT 3. Use the template provided. Download \"TEMPLATE - nats1740a-projectd.docx\" onto your computer and replace TEMPLATE' with your name In the fllename. You . Fill out the template with your ariginal work by doing the following for each section: SECTION A: Academic Honesty Statement [0 marks] This is a mandatory re-affirmation of academic integrity. Read the academic honesty statement found In the template you downloaded above. Indicate you have read the statement and It Is true by typing your name In the space Indicated. If you have already completed the 5 modules about Academic Integrity In Project 1, then you do not need to do them again. Your project will not be marked unless this statement is signed. Additionally, put your full name and student number In the space provided. SECTION B: Short Answer Questions [5 marks] Provide brief answers (in full sentences) to the following questions (no more 150-200 words each), drawings are welcome [f that helps you: 1. What is an exoplanet? [1 mark] 2. What Is the radlal velocity method for finding exoplanets? [2 marks] 3. What is the transit method for finding exoplanets? [2 marks] This must be done In your own words (NO QUOTES). Provide citations to the lectures slides that you used to help answer the questions. See 'How to cite' In the Project 1 - Investigating the Night SKy section of the course's eClass site. SECTION C: Investigating your Light Curve [25 marks] Please place a copy of your Figure 1 - Light Curve at the top of this section. Please also give the Information about your target star that can be found above your Figure 1 - Light Curve. Figure 1 and the accompanying Information about the star will ald the grader when marking. If you do not do this, you will lose 2 marks. Please caption the Figure, and reference the figure as needed. Also feel free to mark It up with labels Iif you believe that's needed. Please note: Figure 2 and Figure 3 do not need to be placed here, and are meant to help you answer questions below. Questions: 1. [2 marks] How many exoplanets are you able to confirm are orbiting your target star? Why are you able to confirm they exist just by looking at the graph. 2ol Relative Brigthness Relative Brigthness Relative Brigthness 1.000 o O o0 0.996 0.994 0.992 0.00 0.05 Figure 1 - Light Curve 0.10 0.15 Time (years) 0.20 1.005 1.000 0.995 0.990 0.985 0.0066 1.005 1.000 0.995 0.990 0.985 0.0068 0.0068 0.0070 Figure 2 - Zoom on one of the exoplanet transits 0.0070 0.0072 0.0074 Time (years) 0.0076 0.0078 Figure 3 - Zoom on the other exoplanet transit 0.0072 0.0074 0.0076 0.0078 Time (years) 0.0080 0.0080 0.0082
