Exosphere Modeling of Proxima b: A Case Study of Photochemical Escape with a Venus-like Atmosphere
Exoplanets orbiting M-dwarfs within habitable zones are exposed to stellar environments more extreme than that terrestrial planets experience in our Solar System, which can significantly impact the atmospheres of the […]

Detectability of Artificial Lights from Proxima b
We investigate the possibility of detecting artificial lights from Proxima b’s dark side by computing light curves from the planet and its host star. The two different scenarios we consider […]
