Guest Speaker: Clarissa Do Ó, Ph.D. candidate – UC San Diego
Summary: In this talk, Clarissa explains that there are different methods that astronomers use to find exoplanets, from the transit method and the radial velocity method to the direct imaging method. This last method uses a coronagraph to cover the light from the star. Clarissa then describes the two main theories of planetary formation, the core accretion model and the gas collapse model. Planets in a planetary system can interact with each other in such a way that their mean motion resonance can disrupt their orbits which can also destabilize their orbits.
This is a fascinating opportunity to learn how astronomers conduct direct imaging of exoplanets. We hope you enjoy it!
