Orbits and Densities of Kepler Planets
Abstract: What have we learned from the thousands of planet candidates discovered by the Kepler satellite? We learn that most, if not all, Kepler planets are closely packed, orbiting in nearly circular, coplanar orbits. We learn that they have masses of order 10 Earth Masses, with densities that span two orders of magnitude. We also infer that most of them were overlaid with hydrogen atmospheres at birth. I will review how these conclusions are obtained. I will also discuss some recent works in deciphering how the Kepler systems are assembled, by studying the overall orbital architecture of these planets.
