Stellar Flares Rather than High As Possible Cause for the Missing Methane in Young Exoplanets: The Case Study of V1298~Tau\,b
Danica Adams, Pierre-Alexis Roy, Hilke Schlichting +1
Recent observations of V1298~Tau\,b, a warm sub-Neptune (R, M, TK) orbiting a young (10-30\,Myr) K star, sho…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Novel Chemical Pathways for the Formation of Nucleobase Precursors via Benzene π-Bond Addition to HCN
Jeehyun Yang, Danica J. Adams, Renyu Hu +1
We propose a simple and efficient pathway for the formation of precursors to core nucleobases in DNA and RNA using a suite of computational chemistry methods. Benzene, which is the…
An Oxidation Gradient Straddling the Small Planet Radius Valley
Collin Cherubim, Robin Wordsworth, Dan Bower +3
We present a population-level view of volatile gas species (H, He, HO, O, CO, CO, CH) distribution during the sub-Neptune to rocky planet transition, revealing…
Reflected-light Phase Curves with PICASO: A Kepler-7b Case Study
Colin D. Hamill, Alexandria V. Johnson, Natasha Batalha +4
Examining reflected light from exoplanets aids in our understanding of the scattering properties of their atmospheres and will be a primary task of future flagship space- and groun…
Greenhouse warming potential of a suite of gas species on early Mars evaluated using a radiative-convective climate model
Jason Jorge, Robin Wordsworth, Danica Adams
Abundant geomorphological and geochemical evidence of liquid water on the surface of early Mars during the late Noachian and early Hesperian periods needs to be reconciled with a f…
The Hubble PanCET Program: A Featureless Transmission Spectrum for WASP-29b and Evidence of Enhanced Atmospheric Metallicity on WASP-80b
Ian Wong, Yayaati Chachan, Heather A. Knutson +19
We present a uniform analysis of transit observations from the Hubble Space Telescope and Spitzer Space Telescope of two warm gas giants orbiting K-type stars - WASP-29b and WASP-8…
Cloudy and Cloud-free Thermal Phase Curves with PICASO: Applications to WASP-43b
Nina Robbins-Blanch, Tiffany Kataria, Natasha E. Batalha +1
We present new functionality within PICASO, a state-of-the-art radiative transfer model for exoplanet and brown dwarf atmospheres, by developing a new pipeline that computes phase-…
Vertical distribution of cyclopropenylidene and propadiene in the atmosphere of Titan
Karen Willacy, SiHe Chen, Danica J. Adams +1
Titan's atmosphere is a natural laboratory for exploring the photochemical synthesis of organic molecules. Significant recent advances in the study of the atmosphere of Titan inclu…
A bimodal distribution of haze in Pluto's atmosphere
Siteng Fan, Peter Gao, Xi Zhang +8
Pluto, Titan, and Triton make up a unique class of solar system bodies, with icy surfaces and chemically reducing atmospheres rich in organic photochemistry and haze formation. Haz…
Spatially Resolved Modeling of Optical Albedos for a Sample of Six Hot Jupiters
Danica Adams, Tiffany Kataria, Natasha Batalha +2
Optical secondary eclipse measurements made by \emph{Kepler} reveal a diverse set of geometric albedos for hot Jupiters with equilibrium temperatures between K. The pre…
The Geographic Distribution of Dense-phase O on Ganymede
Samantha K. Trumbo, Michael E. Brown, Danica Adams
Ground-based spectroscopy of Ganymede's surface has revealed the surprising presence of dense-phase molecular oxygen (O) via weak absorptions at visible wavelengths. To date, t…
A Featureless Infrared Transmission Spectrum for the Super-Puff Planet Kepler-79d
Yayaati Chachan, Daniel Jontof-Hutter, Heather A. Knutson +12
Extremely low density planets ('super-puffs') are a small but intriguing subset of the transiting planet population. With masses in the super-Earth range ( M) and…
Aggregate Hazes in Exoplanet Atmospheres
Danica Adams, Peter Gao, Imke de Pater +1
Photochemical hazes have been frequently used to interpret exoplanet transmission spectra that show an upward slope towards shorter wavelengths and weak molecular features. While p…
