A dark, bare rock for TOI-1685 b from a JWST NIRSpec G395H phase curve
Rafael Luque, Brandon Park Coy, Qiao Xue +9
We report JWST NIRSpec/G395H observations of TOI-1685 b, a hot rocky super-Earth orbiting an M2.5V star, during a full orbit. We obtain transmission and emission spectra of the pla…
Knobs and dials of retrieving JWST transmission spectra. I. The importance of p-T profile complexity
Simon Schleich, Sudeshna Boro Saikia, Quentin Changeat +3
We investigate the impact of using multipoint p-T profiles of varying complexity on the retrieval of synthetically generated hot Jupiter transmission spectra modelled after state-o…
Reliable Detections of Atmospheres on Rocky Exoplanets with Photometric JWST Phase Curves
Mark Hammond, Claire Marie Guimond, Tim Lichtenberg +9
The prevalence of atmospheres on rocky planets is one of the major questions in exoplanet astronomy, but there are currently no published unambiguous detections of atmospheres on a…
Low abundances of TiO and VO on the Dayside of KELT-9 b: Insights from Ground-Based Photometric Observations
Yuya Hayashi, Norio Narita, Akihiko Fukui +21
We present ground-based photometric observations of secondary eclipses of the hottest known planet KELT-9b using MuSCAT2 and Sinistro. We detect secondary eclipse signals in an…
Gliese 12 b: A temperate Earth-sized planet at 12 pc ideal for atmospheric transmission spectroscopy
M. Kuzuhara, A. Fukui, J. H. Livingston +103
Recent discoveries of Earth-sized planets transiting nearby M dwarfs have made it possible to characterize the atmospheres of terrestrial planets via follow-up spectroscopic observ…
Towards atmospheric retrievals of panchromatic light-curves: ExPLOR-ing generalized inversion techniques for transiting exoplanets with JWST and Ariel
Quentin Changeat, Yuichi Ito, Ahmed F. Al-Refaie +2
Conventional atmospheric retrieval codes are designed to extract information, such as chemical abundances, thermal structures and cloud properties, from fully "reduced" spectra obt…
Measuring Tracers of Planet Formation in the Atmosphere of WASP-77A b: Sub-stellar O/H and C/H ratios, with a stellar C/O ratio and a potentially Super-stellar Ti/H ratio
Billy Edwards, Quentin Changeat
We present a comprehensive atmospheric retrieval study of the hot Jupiter WASP-77A\,b using eclipse observations from the Hubble Space Telescope (HST) and JWST. Using atmospheric r…
Is the atmosphere of the ultra-hot Jupiter WASP-121b variable?
Quentin Changeat, Jack W. Skinner, James Y-K. Cho +12
We present a comprehensive analysis of the Hubble Space Telescope observations of the atmosphere of WASP-121 b, a ultra-hot Jupiter. After reducing the transit, eclipse, and phase-…
