Finding Planets Around Bright Stars
Astronomers now know about more than 700 exoplanets and another couple thousand await confirmation. The planetary systems they form are totally unlike ours. Jupiter-sized planets orbiting their stars with periods of a few days, other systems with planets orbiting in a direction opposite to that of the rotation of the star, multi-planet systems with a range of orbital inclinations, and an exoplanet orbiting a stellar binary. These discoveries challenge astronomers' understanding of planet formation; Dr. Simon will describe how theorists are struggling to keep up with the treasure of new discoveries.
