FORMATION OF KUIPER BELT BINARIES BY GRAVITATIONAL COLLAPSE
Kuiper Belt general – planets and satellites formation – protoplanetary disks
2015/12/25
A large fraction of {approx}100 km class low-inclination objects in the classical Kuiper Belt (KB) are binaries with comparable masses and a wide separation of components. A favored model for their fo...
A steady-state model of NEA binaries formed by tidal disruption of gravitational aggregates
Asteroids dynamics Satellites of asteroids
2015/12/25
We present results of a simulation of a steady-state binary near-Earth asteroid (NEA) population. This study combines previous work on tidal disruption of gravitational aggregates [Walsh, K.J., Richar...
A fast method for finding bound systems in numerical simulations:Results from the formation of asteroid binaries
Asteroids Dynamics Data analysis techniques
2015/12/25
We present a new code (companion) that identifies bound systems of particles in O(N logN) time. Simple binaries consisting of pairs of mutually bound particles and complex hierarchies consistingof col...
Imagine living on an exoplanet with two suns. One, you orbit and the other is a very bright, nearby neighbor looming large in your sky. With this “second sun” in the sky, nightfall might be a rare eve...
Dust Grain Evolution in Spatially Resolved T Tauri Binaries
Dust Grain Evolution Spatially Resolved Tauri Binaries
2011/10/10
Core-accretion planet formation begins in protoplanetary disks with the growth of small, ISM dust grains into larger particles. The progress of grain growth, which can be quantified using 10 micron si...
