متن کاملDynamical Simulations of the Planetary System HD69830
The star HD 69830 exhibits radial velocity variations attributed to three planets as well as infrared emission at 8 − 35μm attributed to a warm debris disk. Previous studies have developed models for the planet migration and mass growth (Alibert et al. 2005, 2006) and the replenishment of warm grains (Wyatt et al. 2007). In this paper, we perform n-body integrations in order to explore the impl...
متن کاملThe Formation of Life-sustaining Planets in Extrasolar
Introduction: One of the characteristics that makes Earth a suitable environment for the origin of life is the presence of significant amounts of water and other volatile materials. It is thought that Earth formed by the accretion of a large number of small, rocky planetesimals which formed in the inner part of the Sun’s protoplanetary nebula (Wetherill 1990). However, protoplanetary nebula mod...
متن کاملThe Formation of Jupiter, the Jovian Early Bombardment and the Delivery of Water to the Asteroid Belt: The Case of (4) Vesta
The asteroid (4) Vesta, parent body of the Howardite-Eucrite-Diogenite meteorites, is one of the first bodies that formed, mostly from volatile-depleted material, in the Solar System. The Dawn mission recently provided evidence that hydrated material was delivered to Vesta, possibly in a continuous way, over the last 4 Ga, while the study of the eucritic meteorites revealed a few samples that c...
متن کاملProduction of star-grazing and impacting planetesimals via orbital migration of extrasolar planets
During orbital migration of a giant extrasolar planet via ejection of planetesimals (Murray et al. 1998), inner mean motion resonances can be strong enough to cause planetesimals to graze or impact the star. We integrate numerically the motions of particles which pass through the 3:1 or 4:1 mean motion resonances of a migrating Jupiter mass planet. We find that many particles can be trapped in ...
