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…

JWST NIRSpec finds no clear signs of an atmosphere on TOI-1685 b

Chloe E. Fisher, Matthew J. Hooton, Amélie Gressier +21

Determining the prevalence of atmospheres on terrestrial planets is a core objective in exoplanetary science. While M dwarf systems offer a promising opportunity, conclusive observ…

JWST TRAPPIST-1 e/b Program: Motivation and first observations

Natalie H. Allen, Néstor Espinoza, V. A. Boehm +24

One of the forefront goals in the field of exoplanets is the detection of an atmosphere on a temperate terrestrial exoplanet, and among the best suited systems to do so is TRAPPIST…

JWST-TST DREAMS: The Nightside Emission and Chemistry of WASP-17b

Jacob Lustig-Yaeger, Kristin S. Sotzen, Kevin B. Stevenson +24

Theoretical studies have suggested using planetary infrared excess (PIE) to detect and characterize the thermal emission of transiting and non-transiting exoplanets, however the PI…

JWST-TST DREAMS: Sulfur dioxide in the atmosphere of the Neptune-mass planet HAT-P-26 b from NIRSpec G395H transmission spectroscopy

Amélie Gressier, Natasha E. Batalha, Nicholas Wogan +24

We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 Earth masses, 6.33 Earth radii), based on a single transit observed with th…

JWST-TST DREAMS: NIRSpec/PRISM Transmission Spectroscopy of the Habitable Zone Planet TRAPPIST-1 e

Néstor Espinoza, Natalie H. Allen, Ana Glidden +32

TRAPPIST-1 e is one of the very few rocky exoplanets that is both amenable to atmospheric characterization and that resides in the habitable zone of its star -- located at a distan…
