JWST NIRSpec G395H Transmission Spectra of Two Similar Sub-Neptunes in the TOI-125 System

Yiwei Chai, Néstor Espinoza, Chloe Fisher +10

The James Webb Space Telescope (JWST) has enabled the first in-depth characterisations of sub-Neptune atmospheres, revealing a diversity of chemical compositions and cloud properti…

The First Hubble Detection of a Secondary Eclipse from a Rocky Exoplanet: the 5.4-hour planet TOI-2431 b

Sebastian Zieba, Billy Edwards, Samuel N. Quinn +18

We present an HST/WFC3 G141 phase-curve observation of the ultra-short-period rocky planet TOI-2431 b and detect its secondary eclipse in the near infrared. Combined with the TESS…

JWST MEP - A World Under Spotty Starlight: Detection of CO2 and H2O in the Hot Saturn WASP-52b with JWST NIRSpec G395H

JWST GO 3969 Team, Yanbo Pan, Ryan J. MacDonald +21

Exoplanets orbiting active stars offer distinct challenges for atmospheric characterization with the JWST. Among such worlds, the hot Saturn WASP-52b (Teq 1300 K) orbits an…

Thermal Evolution of Lava Planets Across System Ages: Predictions for Hell of a Survey

Mariana Sastre, Tim Lichtenberg, Lisa Dang +22

Ultra-short-period (USP) rocky exoplanets can have dayside temperatures high enough to maintain permanent magma oceans, sitting at the intersection of interior geophysics and atmos…

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…

WASP-12b Exhibits Persistent In-Transit H Absorption

Shreyas Vissapragada, Fabienne Nail, Morgan MacLeod +6

High-resolution H and He 10830 Å transit spectroscopy can trace the extended upper atmospheres of exoplanets, typically revealing excess in-transit absorption that occurs in the…
