VPLanet: The Virtual Planet Simulator
Rory Barnes, Rodrigo Luger, Russell Deitrick +14
We describe a software package called VPLanet that simulates fundamental aspects of planetary system evolution over Gyr timescales, with a focus on investigating habitable worlds.…
Exo-Milankovitch Cycles II: Climates of G-dwarf Planets in Dynamically Hot Systems
Russell Deitrick, Rory Barnes, Cecilia Bitz +6
Using an energy balance model with ice sheets, we examine the climate response of an Earth-like planet orbiting a G dwarf star and experiencing large orbital and obliquity variatio…
Exo-Milankovitch Cycles I: Orbits and Rotation States
Russell Deitrick, Rory Barnes, Thomas R. Quinn +3
The obliquity of the Earth, which controls our seasons, varies by only ~2.5 degrees over ~40,000 years, and its eccentricity varies by only ~0.05 over 100,000 years. Nonetheless, t…
Stratigraphy of Aeolis Dorsa, Mars: stratigraphic context of the great river deposits
Edwin S. Kite, Alan D. Howard, Antoine S. Lucas +3
Unraveling the stratigraphic record is the key to understanding ancient climate and past climate changes on Mars. River deposits when placed in stratigraphic order could constrain…
Exomoon Habitability and Tidal Evolution in Low-Mass Star Systems
Rhett R. Zollinger, John C. Armstrong, René Heller
Discoveries of extrasolar planets in the habitable zone (HZ) of their parent star lead to questions about the habitability of massive moons orbiting planets in the HZ. Around low-m…
Effects of Extreme Obliquity Variations on the Habitability of Exoplanets
J. C. Armstrong, R. Barnes, S. Domagal-Goldman +3
We explore the impact of obliquity variations on planetary habitability in hypothetical systems with high mutual inclination. We show that large amplitude, high frequency obliquity…
Debris disks as signposts of terrestrial planet formation. II Dependence of exoplanet architectures on giant planet and disk properties
Sean N. Raymond, Philip J. Armitage, Amaya Moro-Martin +6
We present models for the formation of terrestrial planets, and the collisional evolution of debris disks, in planetary systems that contain multiple unstable gas giants. We previo…
The debris disk - terrestrial planet connection
Sean N. Raymond, Philip J. Armitage, Amaya Moro-Martín +5
The eccentric orbits of the known extrasolar giant planets provide evidence that most planet-forming environments undergo violent dynamical instabilities. Here, we numerically simu…
Debris disks as signposts of terrestrial planet formation
Sean N. Raymond, Philip J. Armitage, Amaya Moro-Martín +6
Circumstantial evidence suggests that most known extra-solar planetary systems are survivors of violent dynamical instabilities. Here we explore how giant planet instabilities affe…
