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…
Stellar Contamination Correction Using Back-to-Back Transits of TRAPPIST-1 b and c
Alexander D. Rathcke, Lars A. Buchhave, Julien De Wit +8
Stellar surface heterogeneities, such as spots and faculae, often contaminate exoplanet transit spectra, hindering precise atmospheric characterization. We demonstrate a novel, epo…
Enhancing Exoplanet Ephemerides by Leveraging Professional and Citizen Science Data: A Test Case with WASP-77A b
Federico R. Noguer, Suber Corley, Kyle A. Pearson +42
We present an updated ephemeris and physical parameters for the exoplanet WASP-77 A b. In this effort, we combine 64 ground- and space-based transit observations, 6 space-based ecl…
A Combined Ground-based and JWST Atmospheric Retrieval Analysis: Both IGRINS and NIRSpec Agree The Atmosphere of WASP-77A b is Metal-Poor
Peter Smith, Michael Line, Jacob Bean +12
Ground-based, high-resolution and space-based, low-resolution spectroscopy are the two main avenues through which transiting exoplanet atmospheres are studied. Both methods provide…
JWST transmission spectroscopy of HD 209458b: a super-solar metallicity, a very low C/O, and no evidence of CH4, HCN, or C2H2
Qiao Xue, Jacob L. Bean, Michael Zhang +3
We present the transmission spectrum of the original transiting hot Jupiter HD\,209458b from 2.3 -- 5.1 m as observed with the NIRCam instrument on the James Webb Space Telescop…
Confirmation of sub-solar metallicity for WASP-77Ab from JWST thermal emission spectroscopy
Prune C. August, Jacob L. Bean, Michael Zhang +4
We present the dayside thermal emission spectrum of WASP-77Ab from 2.8 -- 5.2 m as observed with the NIRSpec instrument on the James Webb Space Telescope (JWST). WASP-77Ab was p…
High atmospheric metal enrichment for a Saturn-mass planet
Jacob L. Bean, Qiao Xue, Prune C. August +9
Atmospheric metal enrichment (i.e., elements heavier than helium, also called "metallicity") is a key diagnostic of the formation of giant planets. The giant planets of the solar s…
