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 …
Multiband imaging of the HD 36546 debris disk: a refined view from SCExAO/CHARIS
Kellen Lawson, Thayne Currie, John P. Wisniewski +21
We present the first multi-wavelength (near-infrared; ) imaging of HD 36546's debris disk, using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system co…
The Sonora Substellar Atmosphere Models. II. Cholla: A Grid of Cloud-free, Solar Metallicity Models in Chemical Disequilibrium for the JWST Era
Theodora Karalidi, Mark Marley, Jonathan J. Fortney +5
Exoplanet and brown dwarf atmospheres commonly show signs of disequilibrium chemistry. In the James Webb Space Telescope era high resolution spectra of directly imaged exoplanets w…
Calibration and Performance of the REgolith X-Ray Imaging Spectrometer (REXIS) Aboard NASA's OSIRIS-REx Mission to Bennu
Jaesub Hong, Richard P. Binzel, Branden Allen +23
The REgolith X-ray Imaging Spectrometer (REXIS) instrument on board NASA's OSIRIS-REx mission to the asteroid Bennu is a Class-D student collaboration experiment designed to detect…
Habitability Models for Astrobiology
Abel Méndez, Edgard E. Rivera-Valentín, Dirk Schulze-Makuch +31
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades…
Haze Evolution in Temperate Exoplanet Atmospheres Through Surface Energy Measurements
Xinting Yu, Chao He, Xi Zhang +13
Photochemical hazes are important opacity sources in temperate exoplanet atmospheres, hindering current observations from characterizing exoplanet atmospheric compositions. The haz…
Spatial Distribution of Ultraviolet Emission from Cometary Activity at 67P/Churyumov-Gerasimenko
John W. Noonan, Dominique Bockelée-Morvan, Paul D. Feldman +16
The Alice ultraviolet spectrograph on board the \textit{Rosetta} orbiter provided the first near-nucleus ultraviolet observations of a cometary coma from arrival at comet 67P/Chury…
Analysis of Hybrid Gas-Dust Outbursts Observed at 67P/Churyumov-Gerasimenko
John W. Noonan, Giovanna Rinaldi, Paul D. Feldman +14
Cometary outbursts offer a valuable window into the composition of comet nuclei with their forceful ejection of dust and volatiles in explosive events, revealing the interior compo…
Stumbling over planetary building blocks: AU Microscopii as an example of the challenge of retrieving debris-disk dust properties
Jessica A. Arnold, Alycia J. Weinberger, Gorden Videen +1
We explore whether assumptions about dust grain shape affect resulting estimates of the composition and grain size distribution of the AU Microscopii (AU Mic) debris disk from scat…
How to identify exoplanet surfaces using atmospheric trace species in hydrogen-dominated atmospheres
Xinting Yu, Julianne I. Moses, Jonathan J. Fortney +1
Sub-Neptunes (Rp~1.25-4 REarth) remain the most commonly detected exoplanets to date. However, it remains difficult for observations to tell whether these intermediate-sized exopla…
Longitudinal Variations in the Stratosphere of Uranus from the Spitzer Infrared Spectrometer
Naomi Rowe-Gurney, Leigh N. Fletcher, Glenn S. Orton +5
NASA's Spitzer Infrared Spectrometer (IRS) acquired mid-infrared (5-37 microns) disc-averaged spectra of Uranus very near to its equinox in December 2007. A mean spectrum was const…
A molecular wind blows out of the Kuiper belt
Quentin Kral, J. E. Pringle, Aurélie Guilbert-Lepoutre +9
Gas has been detected in many exoplanetary systems (10 Myr), thought to be released in the destruction of volatile-rich planetesimals orbiting in exo-Kuiper belts. In this lette…
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…
The influence of surface condensation on the evolution of warm and cold rocky planets orbiting Sun-like stars
Irene Bonati, Ramses M. Ramirez
The habitable zone is the region around a star where standing bodies of liquid water can be stable on a planetary surface. Its width is often assumed to be dictated by the efficien…
Chemical variation with altitude and longitude on exo-Neptunes: Predictions for Ariel phase-curve observations
Julianne I. Moses, Pascal Tremblin, Olivia Venot +1
Using 2D thermal structure models and pseudo-2D chemical kinetics models, we explore how atmospheric temperatures and composition change as a function of altitude and longitude wit…
Finding Signs of Life in Transit: High-resolution Transmission Spectra of Earth-like Planets around FGKM Host Stars
Lisa Kaltenegger, Zifan Lin
Thousands of transiting exoplanets have already been detected orbiting a wide range of host stars, including the first planets that could potentially be similar to Earth. The upcom…
Around which stars can TESS detect Earth-like planets? The Revised TESS Habitable Zone Catalog
L. Kaltenegger, J. Pepper, P. M. Christodoulou +3
In the search for life in the cosmos, NASA's Transiting Exoplanet Survey Satellite (TESS) mission has already monitored about 74% of the sky for transiting extrasolar planets, incl…
