TRIDENT: A Rapid 3D Radiative Transfer Model for Exoplanet Transmission Spectra
Ryan J. MacDonald, Nikole K. Lewis
Transmission spectroscopy is one of the premier methods used to probe the temperature, composition, and cloud properties of exoplanet atmospheres. Recent studies have demonstrated…
Sensitivity of the Roman Coronagraph Instrument to Exozodiacal Dust
Ewan S Douglas, John Debes, Bertrand Mennesson +7
Exozodiacal dust, warm debris from comets and asteroids in and near the habitable zone of stellar systems, reveals the physical processes that shape planetary systems. Scattered li…
Hiding in plain sight: observing planet-starspot crossings with the James Webb Space Telescope
Giovanni Bruno, Nikole K. Lewis, Jeff A. Valenti +9
Transiting exoplanets orbiting active stars frequently occult starspots and faculae on the visible stellar disc. Such occultations are often rejected from spectrophotometric transi…
Thermal Phase Curves of XO-3b: an Eccentric Hot Jupiter at the Deuterium Burning Limit
Lisa Dang, Taylor J. Bell, Nicolas B. Cowan +15
We report \textit{Spitzer} full-orbit phase observations of the eccentric hot Jupiter XO-3b at 3.6 and 4.5 m. Our new eclipse depth measurements of ppm at 3.6 …
Gemini/GMOS Transmission Spectroscopy of the Grazing Planet Candidate WD 1856+534 b
Siyi Xu, Hannah Diamond-Lowe, Ryan J. MacDonald +12
WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained fro…
The first retrieval of a substellar subdwarf: A cloud-free SDSS J125637.13-022452.4
Eileen C. Gonzales, Ben Burningham, Jacqueline K. Faherty +5
We present the first retrieval analysis of a substellar subdwarf, SDSS J125637.13-022452.4 (SDSS J1256-0224), using the Brewster retrieval code base. We find SDSS J1256-0224 is bes…
