Surface Volatile Composition as Evidence for Hydrothermal Processes Lasting Longer in Triton's Interior than Pluto's
Kathleen Mandt, Adrienn Luspay-Kuti, Olivier Mousis +1
Ocean worlds, or icy bodies in the outer solar system that have or once had subsurface liquid water oceans, are among the most compelling topics of astrobiology. Typically, confirm…
Solar wind interaction with a comet: evolution, variability, and implication
Charlotte Götz, Jan Deca, Kathleen Mandt +1
Once a cometary plasma cloud has been created through ionisation of the cometary neutrals, it presents an obstacle to the solar wind and the magnetic field within it. The accelerat…
Moonraker -- Enceladus Multiple Flyby Mission
O. Mousis, A. Bouquet, Y. Langevin +50
Enceladus, an icy moon of Saturn, possesses an internal water ocean and jets expelling ocean material into space. Cassini investigations indicated that the subsurface ocean could b…
TRAPPIST-1h as an Exo-Titan. I. The Role of Assumptions about Atmospheric Parameters in Understanding an Exoplanet Atmosphere
Kathleen Mandt, Adrienn Luspay-Kuti, Jacob Lustig-Yaeger +2
The TRAPPIST-1 system is home to at least seven terrestrial planets and is a target of interest for future James Webb Space Telescope (JWST) observations. Additionally, these plane…
The Volatile Carbon to Oxygen Ratio as a Tracer for the Formation Locations of Interstellar Comets
Darryl Z. Seligman, Leslie A. Rogers, Samuel H. C. Cabot +13
Based on the occurrence rates implied by the discoveries of 1I/`Oumuamua and 2I/Borisov, the forthcoming Rubin Observatory Legacy Survey of Space and Time (LSST) should detect $\ge…
The Role of Atmospheric Exchange in False-Positive Biosignature Detection
Ryan C. Felton, Sandra T. Bastelberger, Kathleen E. Mandt +3
Saturn's Moon Titan receives volatiles into the top of its atmosphere-including atomic oxygen-sourced from cryovolcanoes on Enceladus. Similar types of atmosphere exchange from one…
Hierarchical Bayesian Atmospheric Retrieval Modeling for Population Studies of Exoplanet Atmospheres: A Case Study on the Habitable Zone
Jacob Lustig-Yaeger, Kristin S. Sotzen, Kevin B. Stevenson +5
With the growing number of spectroscopic observations and observational platforms capable of exoplanet atmospheric characterization, there is a growing need for analysis techniques…
Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
Retrieving Exoplanet Atmospheres using Planetary Infrared Excess: Prospects for the Nightside of WASP-43 b and other Hot Jupiters
Jacob Lustig-Yaeger, Kevin B. Stevenson, L. C. Mayorga +4
To increase the sample size of future atmospheric characterization efforts, we build on the planetary infrared excess (PIE) technique that has been proposed as a means to detect an…
On the Utility of Transmission Color Analysis I: Differentiating Super-Earths and Sub-Neptunes
Kristin S. Sotzen, Kevin B. Stevenson, Erin M. May +9
The majority of exoplanets found to date have been discovered via the transit method, and transmission spectroscopy represents the primary method of studying these distant worlds.…
Transmission Spectroscopy of the Earth-Sun System to Inform the Search for Extrasolar Life
L. C. Mayorga, J. Lustig-Yaeger, E. M. May +7
Upcoming NASA astrophysics missions such as the James Webb Space Telescope will search for signs of life on planets transiting nearby stars. Doing so will require co-adding dozens…
Cold traps of hypervolatiles in the protosolar nebula at the origin of comet C/2016 R2 (PanSTARRS)'s peculiar composition
Olivier Mousis, Artyom Aguichine, Alexis Bouquet +4
Recent observations of the long period comet C/2016 R2 (PanSTARRS) indicate an unusually high N2/CO abundance ratio, typically larger than 0.05, and at least 2-3 times higher than…
FUV Observations of the Inner Coma of 46P/Wirtanen
John W. Noonan, Walter M. Harris, Steven Bromley +6
Far ultraviolet observations of comets yield information about the energetic processes that dissociate the sublimated gases from their primitive surfaces. Understanding which emiss…
The Fundamental Connections Between the Solar System and Exoplanetary Science
Stephen R. Kane, Giada N. Arney, Paul K. Byrne +7
Over the past several decades, thousands of planets have been discovered outside of our Solar System. These planets exhibit enormous diversity, and their large numbers provide a st…
Escape and evolution of Titan's N atmosphere constrained by N/N isotope ratios
N. V. Erkaev, M. Scherf, S. E. Thaller +4
We apply a 1D upper atmosphere model to study thermal escape of nitrogen over Titan's history. Significant thermal escape should have occurred very early for solar EUV fluxes 100 t…
Modeling Pluto's Minimum Pressure: Implications for Haze Production
Perianne E. Johnson, Leslie A. Young, Silvia Protopapa +6
Pluto has a heterogeneous surface, despite a global haze deposition rate of ~1 micrometer per orbit (Cheng et al., 2017; Grundy et al., 2018). While there could be spatial variatio…
