Results: We will analyze the transits of three stars, as described by Steps 1-4 in the Lab Intro. R1. Let's first analyze Star Capra. a) Measure the maximum transit depth for Star Capra. (1 pt) b) Subtract this number from 1.0 to get the normalized flux difference during transit. (1 pt) c) Use this number to measure the ratio of the planet to star radius. Show your work. (2 pts) d) Consider that Jupiter is about 1/10 the radius of the Sun, Neptune is about 1/30 the radius of the Sun, and Earth is about 1/100 the radius of the Sun. Assuming that the host star for these transits is about the size of the Sun, which of these Solar System planets is the exoplanet you found most similar to? (1 pt)
