Precise Constraints on the Energy Budget of WASP-121 b from its JWST NIRISS/SOSS Phase Curve
Jared Splinter, Louis-Philippe Coulombe, Robert C. Frazier +20
Ultra-hot Jupiters exhibit day-to-night temperature contrasts upwards of 1000 K due to competing effects of strong winds, short radiative timescales, magnetic drag, and H2 dissocia…
Enriched volatiles and refractories but deficient titanium on the dayside atmosphere of WASP-121b revealed by JWST/NIRISS
Stefan Pelletier, Louis-Philippe Coulombe, Jared Splinter +21
With dayside temperatures elevated enough for all atmospheric constituents to be present in gas form, ultra-hot Jupiters offer a unique opportunity to probe the composition of gian…
Horizontal and vertical exoplanet thermal structure from a JWST spectroscopic eclipse map
Ryan C. Challener, Megan Weiner Mansfield, Patricio E. Cubillos +33
Highly-irradiated giant exoplanets known as "ultra-hot Jupiters" are anticipated to exhibit large variations of atmospheric temperature and chemistry as a function of longitude, la…
Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534b
Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald +12
We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with…
