Puffy Venuses: The Mass–Radius Impact of Carbon-rich Atmospheres on Lava Worlds

The Astrophysical Journal
The recent advancements in exoplanet observations enable the potential detection of exo-Venuses, rocky planets with carbon-rich atmospheres. How extended these atmospheres can be, given high carbon abundances, has not been studied.

Examining the Potential for Methyl Halide Accumulation and Detectability in Possible Hycean-type Atmospheres

The Astrophysical Journal Letters
Some sub-Neptune planets may host habitable conditions; for example “Hycean” worlds with H _2 envelopes over liquid water oceans can maintain potentially hospitable pressures and temperatures at their surface.

Atmospheric Retrievals of the Young Giant Planet ROXs 42B b from Low- and High-resolution Spectroscopy

The Astronomical Journal
Previous attempts have been made to characterize the atmospheres of directly imaged planets at low resolution ( R ∼ 10–100 s), but the presence of clouds has often led to degeneracies in the retrieved atmospheric abundances with cloud opacity and ...
