Kronoseismology IV. Six previously unidentified waves in Saturn's middle C ring
M. M. Hedman, P. D. Nicholson, R. G. French
Recent studies of stellar occultations observed by the Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft have demonstrated that multiple spiral wave st…
Chaotic Tides in Migrating Gas Giants: Forming Hot and Transient Warm Jupiters via High-Eccentricity Migration
Michelle Vick, Dong Lai, Kassandra R. Anderson
High-eccentricity migration is an important channel for the formation of hot Jupiters (HJs). In particular, Lidov-Kozai (LK) oscillations of orbital eccentricity/inclination induce…
Hubble PanCET: An extended upper atmosphere of neutral hydrogen around the warm Neptune GJ 3470 b
V. Bourrier, A. Lecavelier des Etangs, D. Ehrenreich +16
GJ 3470b is a warm Neptune transiting an M-dwarf star at the edge of the evaporation desert. It offers the possibility of investigating how low-mass, close-in exoplanets evolve und…
High-Resolution Transit Spectroscopy of Warm Saturns
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +4
We present high-resolution optical transmission spectroscopy of two sub-Saturn mass transiting exoplanets, HAT-P-12b and WASP-69b. With relatively low densities and high atmospheri…
Observation of aerodynamic instability in the flow of a particle stream in a dilute gas
Holly L. Capelo, Jan Molacek, Michiel Lambrechts +5
Forming macroscopic solid bodies in circumstellar discs requires local dust concentration levels significantly higher than the mean. Interactions of the dust particles with the gas…
Ring dynamics around non-axisymmetric bodies with application to Chariklo and Haumea
B. Sicardy, R. Leiva, S. Renner +4
Dense and narrow rings have been discovered recently around the small Centaur object Chariklo and the dwarf planet Haumea, while being suspected around the Centaur Chiron. They are…
Disentangling the planet from the star in late type M dwarfs: A case study of TRAPPIST-1g
Hannah R. Wakeford, Nikole K. Lewis, Julia Fowler +10
The atmospheres of late M stars represent a significant challenge in the characterization of any transiting exoplanets due to the presence of strong molecular features in the stell…
The HST PanCET Program: Hints of Na I & Evidence of a Cloudy Atmosphere for the Inflated Hot Jupiter WASP-52b
Munazza K. Alam, Nikolay Nikolov, Mercedes Lopez-Morales +16
We present an optical to near-infrared transmission spectrum of the inflated hot Jupiter WASP-52b using three transit observations from the Space Telescope Imaging Spectrograph (ST…
Fully scalable forward model grid of exoplanet transmission spectra
Jayesh M. Goyal, Hannah R. Wakeford, Nathan J. Mayne +3
Simulated exoplanet transmission spectra are critical for planning and interpretation of observations and to explore the sensitivity of spectral features to atmospheric thermochemi…
An optical transmission spectrum for the ultra-hot Jupiter WASP-121b measured with the Hubble Space Telescope
Thomas M. Evans, David K. Sing, Jayesh Goyal +24
We present an atmospheric transmission spectrum for the ultra-hot Jupiter WASP-121b, measured using the Space Telescope Imaging Spectrograph (STIS) onboard the Hubble Space Telesco…
Limits on Clouds and Hazes for the TRAPPIST-1 Planets
Sarah E. Moran, Sarah M. Hörst, Natasha E. Batalha +2
The TRAPPIST-1 planetary system is an excellent candidate for study of the evolution and habitability of M-dwarf planets. Transmission spectroscopy observations performed with the…
Planet occurrence rate density models including stellar effective temperature
Daniel Garrett, Dmitry Savransky, Rus Belikov
We present planet occurrence rate density models fit to Kepler data as a function of semi-major axis, planetary radius, and stellar effective temperature. We find that occurrence r…
Approximating Annual Mean Incoming Solar Radiation
Alice Nadeau, Richard McGehee
We derive the Legendre series expansion for the insolation distribution on rapidly rotating planets as a function of sine of the latitude and the planet's obliquity. We give an exp…
Studying the solar system with the International Pulsar Timing Array
R. N. Caballero, Y. J. Guo, K. J. Lee +77
Pulsar-timing analyses are sensitive to errors in the solar-system ephemerides (SSEs) that timing models utilise to estimate the location of the solar-system barycentre, the quasi-…
The Vegetation Red Edge Biosignature Through Time on Earth and Exoplanets
Jack T. O'Malley-James, Lisa Kaltenegger
The high reflection of land vegetation in the near-infrared, the vegetation red edge (VRE), is often cited as a spectral biosignature for surface vegetation on exoplanets. The VRE…
TESS Discovery of an ultra-short-period planet around the nearby M dwarf LHS 3844
Roland Vanderspek, Chelsea X. Huang, Andrew Vanderburg +45
Data from the newly-commissioned \textit{Transiting Exoplanet Survey Satellite} (TESS) has revealed a "hot Earth" around LHS 3844, an M dwarf located 15 pc away. The planet has a r…
The Cassini VIMS archive of Titan: from browse products to global infrared color maps
Stéphane Le Mouélic, Thomas Cornet, Sébastien Rodriguez +11
We have analyzed the complete Visual and Infrared Mapping Spectrometer (VIMS) data archive of Titan. Our objective is to build global surface cartographic products, by combining al…
Dynamical Constraints on the HR 8799 Planets with GPI
Jason J. Wang, James R. Graham, Rebekah Dawson +52
The HR 8799 system uniquely harbors four young super-Jupiters whose orbits can provide insights into the system's dynamical history and constrain the masses of the planets themselv…
Abrupt climate transition of icy worlds from snowball to moist or runaway greenhouse
Jun Yang, Feng Ding, Ramses M. Ramirez +3
Ongoing and future space missions aim to identify potentially habitable planets in our Solar System and beyond. Planetary habitability is determined not only by a planet's current…
