Near-Infrared Transmission Spectroscopy of HAT-P-18b with NIRISS: Disentangling Planetary and Stellar Features in the Era of JWST
Marylou Fournier-Tondreau, Ryan J. MacDonald, Michael Radica +24
The JWST Early Release Observations (ERO) included a NIRISS/SOSS (0.6-2.8m) transit of the 850K Saturn-mass exoplanet HAT-P-18b. Initial analysis of these data…
Atmospheric Reconnaissance of TRAPPIST-1 b with JWST/NIRISS: Evidence for Strong Stellar Contamination in the Transmission Spectra
Olivia Lim, Björn Benneke, René Doyon +22
TRAPPIST-1 is a nearby system of seven Earth-sized, temperate, rocky exoplanets transiting a Jupiter-sized M8.5V star, ideally suited for in-depth atmospheric studies. Each TRAPPIS…
Transit Timing Variations in the three-planet system: TOI-270
Laurel Kaye, Shreyas Vissapragada, Maximilian N. Gunther +69
We present ground and space-based photometric observations of TOI-270 (L231-32), a system of three transiting planets consisting of one super-Earth and two sub-Neptunes discovered…
Another look at the dayside spectra of WASP-43b and HD 209458b: are there scattering clouds?
Jake Taylor, Vivien Parmentier
The search for clouds on the dayside of hot Jupiters has been disadvantaged due to hot Jupiters having a limited number of high quality space-based observations. To date, retrieval…
Characterising a World Within the Hot Neptune Desert: Transit Observations of LTT 9779 b with HST WFC3
Billy Edwards, Quentin Changeat, Angelos Tsiaras +27
We present an atmospheric analysis of LTT 9779 b, a rare planet situated in the hot Neptune desert, that has been observed with HST WFC3 G102 and G141. The combined transmission sp…
Awesome SOSS: Transmission Spectroscopy of WASP-96b with NIRISS/SOSS
Michael Radica, Luis Welbanks, Néstor Espinoza +30
The future is now - after its long-awaited launch in December 2021, JWST began science operations in July 2022 and is already revolutionizing exoplanet astronomy. The Early Release…
