Absence of a Runaway Greenhouse Limit on Lava Planets
The Astrophysical JournalClimate transitions on exoplanets offer valuable insights into the atmospheric processes governing planetary habitability. Previous pure-steam atmospheric models show a thermal limit in outgoing long-wave radiation, which has been used to define the ...

Anatomy of Empirical Transit Spectra of Mars Based on TGO/NOMAD
The Astronomical JournalTransit 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 remains a significant challenge. To

Role of Magma Oceans in Controlling Carbon and Oxygen of Sub-Neptune Atmospheres
The Astrophysical JournalMost exoplanets with a few Earth radii are more inflated than bare-rock planets with the same mass, indicating a substantial volatile amount. Neither the origin of the volatiles nor the planet’s bulk composition can be constrained from the mass–radius ...

Impact of Cosmic Rays on Atmospheric Ion Chemistry and Spectral Transmission Features of TRAPPIST-1e
The Astrophysical JournalOngoing observing projects like the James Webb Space Telescope and future missions offer the chance to characterize Earth-like exoplanetary atmospheres. Thereby, M dwarfs are preferred targets for transit observations, for example, due to their favorable

Six white dwarfs with circumstellar silicates [PDF]
, 2009 Spitzer Space Telescope spectra reveal 10 μm silicate emission from circumstellar dust orbiting six externally polluted white dwarfs. Micron-size glasses with an olivine stoichiometry can account for the distinctively broad wings that extend to 12 μm ...
