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…
Time Resolved Absorption of Six Chemical Species With MAROON-X Points to Strong Drag in the Ultra Hot Jupiter TOI-1518 b
A. Simonnin, V. Parmentier, J. P. Wardenier +27
Wind dynamics play a pivotal role in governing transport processes within planetary atmospheres, influencing atmospheric chemistry, cloud formation, and the overall energy budget.…
Detection of faculae in the transit and transmission spectrum of WASP-69b
D. J. M. Petit dit de la Roche, H. Chakraborty, M. Lendl +9
Context: Transmission spectroscopy is a powerful tool for understanding exoplanet atmospheres. At optical wavelengths, it makes it possible to infer the composition and the presenc…
Differentiable Modeling of Planet and Substellar Atmosphere: High-Resolution Emission, Transmission, and Reflection Spectroscopy with ExoJAX2
Hajime Kawahara, Yui Kawashima, Shotaro Tada +11
Modeling based on differentiable programming holds great promise for astronomy, enabling advanced techniques such as gradient-based posterior sampling and optimization. This paradi…
JWST/NIRISS and HST: Exploring the improved ability to characterise exoplanet atmospheres in the JWST era
Chloe Fisher, Jake Taylor, Vivien Parmentier +6
The Hubble Space Telescope has been a pioneering instrument for studying the atmospheres of exoplanets, specifically its WFC3 and STIS instruments. With the launch of JWST, we are…
The Retrieved Atmospheric Properties of the Sub-stellar Object VHS 1256 b from Analyzing HST, VLT and JWST Spectra
Anna Lueber, Kevin Heng, Brendan P. Bowler +3
Motivated by the observed ~30% variations in flux from the L7 dwarf VHS 1256 b, we subjected its time-resolved Hubble Space Telescope (HST) WFC3 spectra (measured in two epochs in…
