Predicting Outgassing Rates for L 98-59 b with an Interior Model - Astrobiology Research Presentation

Explore a research rotation presentation on predicting outgassing rates for exoplanet L 98-59 b using an interior model. Delve into the importance of JWST observations in characterizing rocky exoplanet atmospheres, particularly those orbiting M-dwarf stars. Examine the use of a revised thermal evolution model to predict outgassing rates for CO2, CO, H2, and H2O, focusing on a stagnant lid carbon cycle regime. Discover preliminary findings suggesting inefficient volatile outgassing, potentially leading to surface temperatures of 800-900 K on L 98-59 b. Gain insights into the challenges and implications of modeling exoplanet interiors and atmospheres in the context of ongoing JWST observations.
