Title: The Transit Age: Planetary Atmospheres, Interiors, and Parent Stars in the Era of JWST
Abstract: JWST observations continue to shine inspiring new insights into the nature of planetary systems across a vast demographic landscape. In this talk, I'll show how these infrared time series data access planetary climates, interiors, orbits, and their coupled evolution. I will share a handful of spectroscopic results, from the largest/hottest planet occulting a blue subgiant, to the smallest/coldest planet transiting a red dwarf. I will demonstrate how these stellar exoplanet datasets can be assembled to characterize the parent star to an unprecedented degree, yielding state-of-the-art age constraints for nearly a dozen giant planet systems thus far. Lastly, I'll zoom out and synthesize how atmospheric spectra, ages, and refined stellar characteristics will help us understand the diverse and evolving inner lives of giant planets over the coming decade.
If you have any questions, contact the PALS hosts: Benjamin Sharkey (small bodies) and Matt Nixon (exoplanets).
SPECIAL ACCOMMODATIONS:Special accommodations for individuals with disabilities can be made by calling (301) 405-3001. It would be appreciated if we are notified at least one week in advance.
ATL 1250 is a flat, carpeted conference room that can accommodate approximately 20-30 people at large tables. The closest wheelchair accessible entry to this room in the Atlantic building is the white stone entrance at 224 Stadium Drive.
