Network and Kinetics-based Biosignatures: Implications for the Putative Habitable World Observatory Design
Theresa Fisher, Chester Harman, Estelle Janin +4
The proposed Habitable Worlds Observatory is intended to observe the atmospheres of nearby terrestrial exoplanets with a resolution greater than that of any previous instrument. Wh…
Generative AI for Overall Mission Effectiveness at the Habitable Worlds Observatory
Megan Shabram, Ryan McClelland, John Wu +14
Here we present several use cases for using Generative AI (Gen AI) to improve systems engineering and cognitive knowledge management related to the future of astronomy from a culmi…
The Occurrence of Rocky Habitable Zone Planets Around Solar-Like Stars from Kepler Data
Steve Bryson, Michelle Kunimoto, Ravi K. Kopparapu +79
We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar prop…
Sensitivity Analyses of Exoplanet Occurrence Rates from Kepler and Gaia
Megan Shabram, Natalie Batalha, Susan E. Thompson +11
We infer the number of planets-per-star as a function of orbital period and planet size using archival data products with updated stellar properties from the Data R…
The Eccentricity Distribution of Short-Period Planet Candidates Detected by Kepler in Occultation
Megan Shabram, Brice-Olivier Demory, Jessi Cisewski +2
We characterize the eccentricity distribution of a sample of ~50 short-period planet candidates using transit and occultation measurements from NASA's Kepler Mission. First, we eva…
The Evolution of Circumplanetary Disks around Planets in Wide Orbits: Implications for Formation Theory, Observations, and Moon Systems
Megan Shabram, Aaron Boley
Using radiation hydrodynamics simulations, we explore the evolution of circumplanetary disks around wide-orbit proto-gas giants. At large distances from the star (~100 AU), gravita…
Doppler Signatures of the Atmospheric Circulation on Hot Jupiters
Adam P. Showman, Jonathan J. Fortney, Nikole K. Lewis +1
The meteorology of hot Jupiters has been characterized primarily with thermal measurements, but recent observations suggest the possibility of directly detecting the winds by obser…
Constraining the Planetary System of Fomalhaut Using High-Resolution ALMA Observations
Aaron C. Boley, Matthew J. Payne, Stuartt Corder +3
The dynamical evolution of planetary systems leaves observable signatures in debris disks. Optical images trace micron-sized grains, which are strongly affected by stellar radiatio…
Disequilibrium Carbon, Oxygen, and Nitrogen Chemistry in the Atmospheres of HD 189733b and HD 209458b
Julianne I. Moses, Channon Visscher, Jonathan J. Fortney +8
We have developed 1-D photochemical and thermochemical kinetics and diffusion models for the transiting exoplanets HD 189733b and HD 209458b to study the effects of disequilibrium…
Transmission Spectra of Transiting Planet Atmospheres: Model Validation and Simulations of the Hot Neptune GJ 436b for JWST
Megan Shabram, Jonathan J. Fortney, Thomas P. Greene +1
We explore the transmission spectrum of the Neptune-class exoplanet GJ 436b, including the possibility that its atmospheric opacity is dominated by a variety of non- equilibrium ch…
Probing potassium in the atmosphere of HD 80606b with tunable filter transit spectrophotometry from the Gran Telescopio Canarias
Knicole D. Colon, Eric B. Ford, Seth Redfield +4
We report observations of HD 80606 using the 10.4-m Gran Telescopio Canarias (GTC) and the OSIRIS tunable filter imager. We acquired very-high-precision, narrow-band photometry in…
