Terrestrial Planet Formation in Binary Star Systems
More than half of all main sequence stars, and an even larger fraction of pre-main sequence stars, reside in binary/multiple star systems [1, 2]. Numerical simulations of the collapse of molecular cloud cores to form binary stars suggest that disks form within binary star systems [3]. The presence of disk material has been indirectly observed around one or both components of some young binary s...
متن کاملHabitable Planet Formation in Binary-Planetary Systems
Recent radial velocity observations have indicated that Jovian-type planets can exist in moderately close binary star systems. Numerical simulations of the dynamical stability of terrestrial-class planets in such environments have shown that, in addition to their giant planets, these systems can also harbor Earth-like objects. In this paper, we study the late stage of terrestrial planet formati...
متن کاملTerrestrial Planet Formation Around Individual Stars Within Binary Star Systems
We calculate herein the late stages of terrestrial planet accumulation around a solar type star that has a binary companion with semimajor axis larger than the terrestrial planet region. We perform more than one hundred simulations to survey binary parameter space and to account for sensitive dependence on initial conditions in these dynamical systems. As expected, sufficiently wide binaries le...
متن کاملTerrestrial 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 کاملPlanet Formation in Binary Stars : The case of γ Cep
Context. Over 30 planetary systems have been discovered to reside in binary stars. As some of the binary separations are smaller than 20 astronomical units (AU) the gravitational perturbation of the secondary star has a very strong influence on the planet formation process, as it truncates the protoplanetary disk, possibly shortens its lifetime, and stirs up the embedded planetesimals. Due to i...
