Terrestrial Planet Formation Surrounding Close Binary Stars
Most stars reside in binary/multiple star systems; however, previous models of planet formation have studied growth of bodies orbiting an isolated single star. Disk material has been observed around both components of some young close binary star systems. Additionally, it has been shown that if planets form at the right places within such disks, they can remain dynamically stable for very long ...
متن کاملLow–Mass Proto–Planet Migration in T-Tauri α–Disks
We present detailed estimates of “type-I” migration rates for low-mass proto-planets embedded in steady-state T-Tauri α–disks, based on Lindblad torque calculations ignoring feedback on the disk. Differences in migration rates for several plausible background disk models are explored and we contrast results obtained using the standard two dimensional formalism of spiral density wave theory with...
متن کاملTerrestrial Planet Formation
The standard planetesimal model of terrestrial-planet formation is based on astronomical and cosmochemical observations, and the results of laboratory experiments and numerical simulations. In this model, planets grow in a series of stages beginning with the μm-sized dust grains observed in protoplanetary disks. Dust grains readily stick together to form mm-to-cm-sized aggregates, some of which...
متن کاملTerrestrial planet formation.
Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets. This information helps to guide numerical models for the three stages of planet formation from dust to planetesimals (~10...
متن کاملEarth and Terrestrial Planet Formation
The growth and composition of Earth is a direct consequence of planet formation throughout the Solar System. We discuss the known history of the Solar System, the proposed stages of growth and how the early stages of planet formation may be dominated by pebble growth processes. Pebbles are small bodies whose strong interactions with the nebula gas lead to remarkable new accretion mechanisms for...
