Atmospheric Reconnaissance of TRAPPIST-1 f with JWST NIRISS SOSS: No Evidence for the Transit Light Source Effect
Olivia Lim, René Doyon, Ryan J. MacDonald +25
In just over three years of operation, JWST has observed all seven planets of the TRAPPIST-1 system. The two innermost planets were found to have little to no atmosphere, barring t…
High-Resolution Dayside Spectroscopy of the Ultra-Hot Jupiter WASP-178b with GHOST/Gemini South
Caitlin E. Bell, Emily K. Deibert, Adam B. Langeveld +4
We present high-resolution dayside spectroscopy of the ultra-hot Jupiter WASP-178b obtained with the Gemini High-resolution Optical SpecTrograph (GHOST) at the Gemini South Observa…
Accretion Properties of the Young Brown Dwarf 2MASS J08440915-7833457
Toni V. Panzera, Laura S. Flagg, Margaret A. Mueller +2
We present HST-COS FUV and -STIS optical observations towards the young accreting brown dwarf 2MASS-J08440915-7833457 (J0844) from the ULLYSES DDT Program. We analyse hot FUV lines…
Diversity in the haziness and chemistry of temperate sub-Neptunes
Pierre-Alexis Roy, Björn Benneke, Marylou Fournier-Tondreau +17
Recent transit observations of K2-18b and TOI-270d revealed strong molecular absorption signatures, lending credence to the idea that temperate sub-Neptunes (T=250-40…
Separating flare and secondary atmospheric signals with RADYN modeling of near-infrared JWST transmission spectroscopy observations of TRAPPIST-1
Ward S. Howard, Adam F. Kowalski, Michael Radica +10
Although TRAPPIST-1's temperate planets have the highest transmission signals of any known system, flares contaminate 50-70% of transits at the 1000 ppm level, far above 100 ppm se…
Discovery of an Accretion Burst in a Free-Floating Planetary-Mass Object
V. Almendros-Abad, A. Scholz, B. Damian +7
We report the discovery of a long-lasting burst of disk accretion in Cha J11070768-7626326 (Cha 1107-7626), a young, isolated, 5-10 M object. In spectra taken…
