Characterizing the Atmospheres of Low Surface Gravity M-dwarfs

This study focuses on characterizing the atmospheres of low surface gravity M-dwarfs, which are promising hosts for exoplanets. The research delves into why low gravity M-dwarfs appear brighter in the infrared than typical M-dwarfs, presenting an improved base model with added opacities. The finding
