Anatomy Of Empirical Transit Spectra Of Mars Based On TGO/NOMAD
Transit spectroscopy is a powerful tool for probing atmospheric structures of exoplanets. Accurately accounting for the effects of aerosols is key to reconstructing atmospheric properties from transit spectra, yet this […]

Photo-dynamical Analysis of Circumbinary Multi-planet System TOI-1338: a Fully Coplanar Configuration with a Puffy Planet
TOI-1338 is the first circumbinary planet system discovered by TESS. It has one transiting planet at P∼95 day and an outer non-transiting planet at P∼215 day complemented by RV observation.

The Open-source Sunbather Code: Modeling Escaping Planetary Atmospheres And Their Transit Spectra
Atmospheric escape is thought to significantly influence the evolution of exoplanets, especially for sub-Jupiter planets on short orbital periods. Theoretical models predict that hydrodynamic escape could erode the atmospheres of […]
