The Pandora SmallSat: Target Selection and Early Science
Emily A. Gilbert, Elisa V. Quintana, Jessie L. Dotson +41
The Pandora spacecraft is a smallsat selected in NASA's inaugural class of Pioneers missions. The aim of the Pandora mission is to disentangle stellar activity signals from exoplan…
An Evolving Cosmic Shoreline and Sandbar Bounding the Rocky Airless Valley
Barron K. Nguyen, Laura K. Schaefer, Xuan Ji +7
Recent JWST observations challenge the traditional 'cosmic shoreline' from both sides, revealing thick volatile atmospheres on the hottest close-in 'lava worlds,' where irradiation…
Evidence for an Atmosphere on the Ultra-Short Period super-Earth HD 3167 b
Brandon Park Coy, Qiao Xue, Megan Weiner Mansfield +14
'Lava worlds'-Earth-sized planets hot enough (Teq >~ 1100 K) to melt their dayside silicate surfaces-have emerged as promising candidates for atmospheric detection and characteriza…
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…
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…
No Thick Atmosphere on the Terrestrial Exoplanet Gl 486b
Megan Weiner Mansfield, Qiao Xue, Michael Zhang +8
A primary science goal for JWST is to detect and characterize the atmospheres of terrestrial planets orbiting M dwarfs (M-Earths). The existence of atmospheres on M-Earths is highl…
Geodynamics of super-Earth GJ 486b
Tobias G. Meier, Dan J. Bower, Tim Lichtenberg +8
Many super-Earths are on very short orbits around their host star and, therefore, more likely to be tidally locked. Because this locking can lead to a strong contrast between the d…
Phase-resolving the absorption signatures of water and carbon monoxide in the atmosphere of the ultra-hot Jupiter WASP-121b with GEMINI-S/IGRINS
Joost P. Wardenier, Vivien Parmentier, Michael R. Line +12
Ultra-hot Jupiters are among the best targets for atmospheric characterization at high spectral resolution. Resolving their transmission spectra as a function of orbital phase offe…
IGRINS observations of WASP-127 b: HO, CO, and super-Solar atmospheric metallicity in the inflated sub-Saturn
Krishna Kanumalla, Michael R. Line, Megan Weiner Mansfield +6
High resolution spectroscopy of exoplanet atmospheres provides insights into their composition and dynamics from the resolved line shape and depth of thousands of spectral lines. W…
The metallicity and carbon-to-oxygen ratio of the ultra-hot Jupiter WASP-76b from Gemini-S/IGRINS
Megan Weiner Mansfield, Michael R. Line, Joost P. Wardenier +11
Measurements of the carbon-to-oxygen (C/O) ratios of exoplanet atmospheres can reveal details about their formation and evolution. Recently, high-resolution cross-correlation analy…
Two-Dimensional Eclipse Mapping of the Hot Jupiter WASP-43b with JWST MIRI/LRS
Mark Hammond, Taylor J. Bell, Ryan C. Challener +21
We present eclipse maps of the two-dimensional thermal emission from the dayside of the hot Jupiter WASP-43b, derived from an observation of a phase curve with the JWST MIRI/LRS in…
