WINERED Detects a Strong Atmospheric Outflow on the Sub-Neptune GJ 3090b

Shreyas Vissapragada, Zifan Lin, Annabella Meech +12

Sub-Neptunes are the most common short-period ( d) planets known. A major goal for the field is to build a comprehensive understanding of their compositions and evolutionary…

Evolutionary pathways toward survival of a thick CO2- or SO2-rich atmosphere on the lava world TOI-561 b

Emma Postolec, Tim Lichtenberg, Johanna K. Teske +10

Rocky planets evolve through the exchange of volatiles between their interiors and atmospheres, an interplay still poorly constrained by observations. Remarkably, highly irradiated…

A Highly Reflective Atmosphere on the Lava World TOI-561b Revealed by JWST/NIRSpec Phase Curve

Samuel Boucher, Lisa Dang, Alex McGinty +15

Ultra-short period (USP) rocky planets are expected to be depleted of any substantial gaseous envelope due to the intense irradiation they receive from their host star, making the…

Magnesium silicate condensation in sub-Neptune envelopes: the fundamental link between chemistry, structure, and observables

William Misener, Peter Gao, Nicole L. Wallack +2

Chemical interactions between the hydrogen-dominated envelopes and silicate-rich interiors of sub-Neptunes likely play a key role in shaping their atmospheric structure, mass-radiu…

GEMS JWST: Hold on to your HATS(-6 b), a sub-solar metallicity giant planet with water, methane and ammonia in its atmosphere

Giannina Guzmán Caloca, Caleb I. Cañas, Nicole L. Wallack +16

HATS-6 b is one of several recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) and is part of a JWST survey that aims to compare bulk and atmospheric properties of t…

A Sulfur-Rich Atmosphere for the Young Jupiter Analog AF Lep b Reveals Significant Solid Accretion

Jerry W. Xuan, William O. Balmer, Yayaati Chachan +25

AF Lep b is one of the closest analogs to Jupiter in terms of mass () and semi-major axis ( AU) amenable to spectroscopic characterization. We present JWST/NIR…
