A Spatial Map of the Atmospheric Limb of a Hot Jupiter

Lili Alderson, Hannah R. Wakeford, David Grant +18

Planets are inherently three-dimensional objects shaped by their thermal structure and dynamics. Observations of transiting exoplanets have begun to uncover this three-dimensional…

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…

Hot Rocks Survey VI: An anomalously hot dayside for the rocky planet GJ 357 b

Merlin Zgraggen, Brice-Olivier Demory, Hannah Diamond-Lowe +15

As part of the JWST Hot Rocks Survey, we analyzed a JWST/MIRI F1500W secondary-eclipse observation of GJ 357 b, a rocky exoplanet orbiting a nearby M dwarf. We also performed a new…

Uncovering temperate worlds: an updated look at the K2-3 system with ESPRESSO

Avidaan Srivastava, Emma Pimentel, Amélie Gressier +24

The K2-3 system is one of the most unique planetary systems as it features three transiting sub-Neptunes in decreasing order of radii, spanning the radius valley. In addition to th…

No Persistent Helium Absorption in LHS 1140 b: Four JWST/NIRISS SOSS Transits and Multi-epoch Stellar He I Variability

Amélie Gressier, Charles Cadieux, René Doyon +4

The search for atmospheres on temperate terrestrial planets is important for understanding how these objects form and evolve, and their potential habitability. Recent transit obser…

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

Måns Holmberg, Hannah Diamond-Lowe, João M. Mendonça +16

JWST is transforming our ability to characterise small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmo…
