The Compositional Diversity of Extrasolar Terrestrial Planets: II. Migration Simulations
Jade C. Carter-Bond, David P. O'Brien, Sean N. Raymond
Prior work has found that a variety of terrestrial planetary compositions are expected to occur within known extrasolar planetary systems. However, such studies ignored the effects…
Delivery of Dark Material to Vesta via Carbonaceous Chondritic Impacts
Vishnu Reddy, Lucille Le Corre, David P. O'Brien +22
NASA's Dawn spacecraft observations of asteroid (4) Vesta reveal a surface with the highest albedo and color variation of any asteroid we have observed so far. Terrains rich in low…
Outcomes and Duration of Tidal Evolution in a Star-Planet-Moon System
Takashi Sasaki, Jason W. Barnes, David P. O'Brien
We formulated tidal decay lifetimes for hypothetical moons orbiting extrasolar planets with both lunar and stellar tides. Previous work neglected the effect of lunar tides on plane…
A low mass for Mars from Jupiter's early gas-driven migration
Kevin J. Walsh, Alessando Morbidelli, Sean N. Raymond +2
Jupiter and Saturn formed in a few million years (Haisch et al. 2001) from a gas-dominated protoplanetary disk, and were susceptible to gas-driven migration of their orbits on time…
Low Mg/Si planetary host stars and their Mg-depleted terrestrial planets
Jade C. Carter-Bond, David P. O'Brien, Elisa Delgado Mena +3
Simulations have shown that a diverse range of extrasolar terrestrial planet bulk compositions are likely to exist, based on the observed variations in host star elemental abundanc…
