JWST COMPASS: A NIRSpec G395H Transmission Spectrum of the Super-Earth GJ 357 b

The Astronomical Journal
We present JWST NIRSpec/G395H transmission spectroscopy observations of GJ 357 b, a warm ( T _eq  ≈ 525 K) super-Earth (1.2 R _⊕ , 1.84 M _⊕ ) orbiting a nearby M3-type star, with a median precision of 18 ppm and 27 ppm in NRS1 and NRS2, respectively ...

Hot Rocks Survey. V. Secondary Eclipse Photometry of GJ 3473 b with JWST/MIRI

The Astronomical Journal
JWST is transforming our ability to characterize small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmospheres or are stripped bare by stellar irradiation—a boundary that ...

Synergistic Effects of Ocean Salinity and Planetary Obliquity Enhance Habitability of Cold Exo-Earths

The Astrophysical Journal
Past work has shown that ocean salinity and planetary obliquity both influence the climates of Earth-like exoplanets throughout the habitable zone of Sun-like stars.

The Coupled Impacts of Atmospheric Composition and Obliquity on the Climate Dynamics of TRAPPIST-1e

The Astrophysical Journal
Planets in multiplanet systems are expected to migrate inward as near-resonant chains, thus allowing them to undergo gravitational planet–planet interactions and possibly maintain a nonzero obliquity.

A New 2D Energy Balance Model for Simulating the Climates of Rapidly and Slowly Rotating Terrestrial Planets

The Planetary Science Journal
Energy balance models (EBMs), alongside radiative–convective climate models and global climate models (GCMs), are useful tools for simulating planetary climates.
