Document Summary
The final exam structure is the same as the midterm, 7 sa and 40-50 multiple choice. covers the whole course. The radial velocity method allows us to measure the mass and period of planets orbiting the sun. Most of the planets observed in the radial velocity method are giant jupiters. The transit method is where the planet goes infront of the host star and blocks some light,and we look at that light. As planets pass infront of stars, we see different kinds of light. When the planet starts passing infront of the star, light drops off, and when its in the middle of the star, theres the minimum brightness. When the planet goes behind the star, theres 2 effects. The planet could be emitting its own light changing the light, or the planet is reflecting the star light, causing a secondary drop in the light curve.
