To perform the folding, you will use the spreadsheet's MOD function on the Time variable to create a new variable, Day of Transit (your instructors will show you how). You will then create a new sheet and copy the Day of Transit into Sheet 2. You will also copy the Flux into Sheet 2. Graph the Light flux against the Day of Transit to obtain a light curve that shows the transit in detail. Insert a copy of the transit curve in this document here 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)>, where Rs is the size of the exoplanets 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. RO= Rsun = Rjup (Multiply Rsun by 10 to get Rjup.)
