Helium escaping from the atmosphere of a nearby rocky exoplanet orbiting in a habitable zone

Collin Cherubim, Shreyas Vissapragada, Tim Cunningham +13

Observations of highly irradiated gas giant exoplanets have shown helium escaping from their atmospheres. There is limited evidence for atmospheres on rocky exoplanets, perhaps bec…

Stringent Upper Bounds on Atmospheric Mass Loss from Three Neptune-Sized Planets in the TOI-4010 System

Morgan Saidel, Shreyas Vissapragada, Michael Zhang +6

Photoevaporative models predict that the lower edge of the Neptune desert is sculpted by atmospheric mass loss. However, the stellar high energy fluxes that power hydrodynamic esca…

Clouds and Hazes in GJ 1214b's Metal-Rich Atmosphere

Isaac Malsky, Emily Rauscher, Kevin Stevenson +10

The sub-Neptune GJ 1214b has an infamously flat transmission spectrum, likely due to thick aerosols in its atmosphere. A recent JWST MIRI spectroscopic phase curve of GJ 1214 b add…

Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet

Guangwei Fu, Luis Welbanks, Drake Deming +15

As the closest transiting hot Jupiter to Earth, HD 189733b has been the benchmark planet for atmospheric characterization. It has also been the anchor point for much of our theoret…

A secondary atmosphere on the rocky exoplanet 55 Cancri e

Renyu Hu, Aaron Bello-Arufe, Michael Zhang +14

Characterizing rocky exoplanets is a central endeavor of astronomy, and yet the search for atmospheres on rocky exoplanets has hitherto resulted in either tight upper limits on the…

Atmospheric Mass Loss from TOI-1259 A b, a Gas Giant Planet With a White Dwarf Companion

Morgan Saidel, Shreyas Vissapragada, Jessica Spake +6

The lack of close-in Neptune-mass exoplanets evident in transit surveys has largely been attributed either to photoevaporative mass loss or high-eccentricity migration. To distingu…
