Aerosols and hydrocarbons in the atmosphere of a white dwarf planet
Ryan J. MacDonald, Christopher E. O'Connor, Victoria A. Boehm +15
Most stars, including our Sun, will one day evolve into red giants and, subsequently, white dwarfs. Several planet candidates have recently been identified orbiting white dwarfs, d…
JWST-TST DREAMS: The Nightside Emission and Chemistry of WASP-17b
Jacob Lustig-Yaeger, Kristin S. Sotzen, Kevin B. Stevenson +24
Theoretical studies have suggested using planetary infrared excess (PIE) to detect and characterize the thermal emission of transiting and non-transiting exoplanets, however the PI…
Additional JWST/NIRSpec Transits of the Rocky M Dwarf Exoplanet GJ 1132 b Reveal a Featureless Spectrum
Katherine A. Bennett, Ryan J. MacDonald, Sarah Peacock +17
As an archetypal M-dwarf rocky exoplanet, GJ 1132 b has a varied history of atmospheric measurements. At 1.13 , 1.66 , and 580 K, it orbits a bright…
Characterizing the Dynamics and Chemistry of Transiting Exoplanets with the Habitable World Observatory
Hannah R. Wakeford, Laura C. Mayorga, Joanna K. Barstow +7
The primary scientific objective of this Habitable Worlds Observatory (HWO) Science Case Development Document (SCDD) is to measure planetary rotation rates of transiting exoplanets…
Cloudy mornings and clear evenings on a gas giant exoplanet
Sagnick Mukherjee, David K. Sing, Guangwei Fu +25
The spectra of exoplanet atmospheres are affected by aerosols (clouds and hazes) of uncertain origin. Proposed aerosol formation mechanisms include gas condensation or photochemica…
Stellar Models Also Limit Exoplanet Atmosphere Studies in Emission
Thomas J. Fauchez, Elsa Ducrot, Benjamin V. Rackham +3
Stellar contamination has long been recognized as a major bottleneck in transmission spectroscopy, limiting our ability to accurately characterize exoplanet atmospheres-particularl…
Spectroscopically resolved partial phase curve of the rapid heating and cooling of the highly-eccentric Hot Jupiter HAT-P-2b with WFC3
Bob Jacobs, Jean-Michel Désert, Nikole Lewis +10
The extreme environments of transiting close-in exoplanets in highly-eccentric orbits are ideal for testing exo-climate physics. Spectroscopically resolved phase curves not only al…
JWST/NIRCam Transmission Spectroscopy of the Nearby Sub-Earth GJ 341b
James Kirk, Kevin B. Stevenson, Guangwei Fu +17
We present a JWST/NIRCam transmission spectrum from m of the recently-validated sub-Earth GJ 341b ( , …
The Dark World: A Tale of WASP-43b in Reflected Light with HST WFC3/UVIS
Jonathan Fraine, Laura C. Mayorga, Kevin B. Stevenson +14
Optical, reflected light eclipse observations provide a direct probe of the exoplanet scattering properties, such as from aerosols. We present here the photometric, reflected light…
