Now you can measure the drop in flux at the middle of the transit. Drop in flux = AF __. The drop in flux is related to the size of the exoplanet, Rp. AF = (Rp/Rs)z, where Rs is the size of the exoplanet's star. You are given the size of the star in terms of the size of the Sun: Rs = 1.793 Rsun. Use the size of the star and the drop in flux to find the size of the planet. Rp=__Rsun = __ Rjup (Multiply Rsun by 10 to get Rjup.) C. Semimajor Axis The exoplanet orbital period and the mass of the star allow us to determine the semimajor axis (distance from the star) of the exoplanet using Kepler's third law: P2=a3/Ms, where Ms is the mass of the star in solar masses. You have the period from part A, but you must convert it into years by dividing by 365.25: Period = __days = __ years. You are given the mass of the star in solar masses: Ms =1.347 Msun. Use the period, the mass of the star, and Kepler's third law to find the semimajor axis. a=__ AU
