The HST/WFC3 Transmission Spectrum of AU Mic b Part I: An Atmosphere Obscured by Contamination and Systematics

William C. Waalkes, Peter Gao, Elisabeth Newton +10

Young sub-Neptune progenitors around M dwarfs offer an excellent opportunity to probe the formation of their abundant, older cousins. At 20 Myr and only 9.7 pc away, AU Mic b…

Atmospheric Escape Rates from Mars - If it Orbited an Old M-Dwarf Star

David A. Brain, Ofer Cohen, Thomas E. Cravens +35

Atmospheric escape is an important process that influences the evolution of planetary atmospheres. A variety of physical mechanisms can contribute to escape from an atmosphere, inc…

A Panchromatic JWST Spectrum of a Giant Starspot on the Fully Convective M-dwarf TOI-3884

C. A. Murray, L. Garcia, B. V. Rackham +18

TOI-3884 b is a rare super-Neptune transiting a fully convective M dwarf that hosts a persistent giant polar spot. Because the planet occults this active region during every transi…

Quantifying the Impact of Starspot-Crossing Events on Retrieved Parameters from Transit Lightcurves

C. A. Murray, Z. Berta-Thompson

Starspot-crossing events (SCEs) in exoplanet transit lightcurves are becoming increasingly common as we focus on cooler host stars and observe higher precision photometric and spec…
