Planetary and exoplanetary Lunch Seminar (PALS) for 2023-11-13

Series: Planetary and exoplanetary Lunch Seminar (PALS)
Date: Monday 13-Nov-2023
Time: 11:15 am-12:15 pm
Location: ATL 1250 and Zoom (contact host Matt Nixon for link)
Speaker: Shubham Kanodia (Carnegie EPL)
Title: Searching for GEMS – Giant Exoplanets around M-dwarf Stars

Abstract: Giant (gaseous) exoplanets around M-dwarf stars (GEMS) represent an extreme of planet formation, attributed to the theorized difficulty in forming them. I will share preliminary results from the Searching for Giant Exoplanets around M-dwarf Stars survey, which includes a sample of a million M-dwarfs, and is expected to find 50–100 transiting GEMS while providing accurate estimates of their occurrence as a function of stellar mass. I will discuss how this sample has started to challenge our understanding of giant planet formation around low-mass stars and discuss exciting new trends in giant planet bulk properties across different samples. I will also present new results exploring gravitational instability as a means of rapid GEMS formation. Finally, I will discuss future prospects and the potential of this sample, including our JWST Cycle 2 program to study 7 GEMS, characterize their atmospheres, and determine their bulk metallicity.

If you have any questions, contact the PALS hosts: Jacob Kloos (small bodies) and Matt Nixon (exoplanets).
