The Fiery Fate of Exoplanets

Speaker: Joleen Carlberg (Space Telescope Science Institute)
What happens to planets when their stars begin to die? For many planets discovered outside of our Solar System, the answer is a trip into the fiery depths of their host star. The most successful ways that astronomers discover exoplanets are biased towards finding both large planets and planets orbiting close to their host stars. Consequently, the population of known exoplanets includes a sizeable subpopulation of massive planets in tiny orbits. During the late stages of its life, a star will expand 10 to 100 times - well beyond the orbits of many of these exoplanets. Such planetary engulfment can alter the properties of the host star. Dr. Carlberg will discuss various scenarios of these planet swallowing events as well as the observational clues they may leave behind.
The 2019 Public Lecture Series offers talks on a diverse selection of cosmic topics held the first Tuesday of every month in the STScI John N. Bahcall Auditorium. Admission is free and free parking is available in the lot across the street. Find information related to driving directions and relevant transportation resources on our Getting Here page.
