Rapid Elimination of Small Dust Grains in Molecular Clouds
Kedron Silsbee, Alexei Ivlev, Paola Caselli +2
We argue that impact velocities between dust grains with sizes less than in molecular cloud cores are dominated by drift arising from ambipolar diffusion. This effe…
O(N^2) fragmentation algorithm
Roman R. Rafikov, Kedron Silsbee, Richard A. Booth
Collisional fragmentation is a ubiquitous phenomenon arising in a variety of astrophysical systems, from asteroid belts to debris and protoplanetary disks. Numerical studies of fra…
Gas and dust temperature in pre-stellar cores revisited: New limits on cosmic-ray ionization rate
Alexei V. Ivlev, Kedron Silsbee, Olli Sipilä +1
We develop a self-consistent model for the equilibrium gas temperature and size-dependent dust temperature in cold, dense pre-stellar cores, assuming an arbitrary power-law size di…
Chondrule Formation by the Jovian Sweeping Secular Resonance
Munan Gong, Xiaochen Zheng, Douglas N. C. Lin +3
Chondrules are silicate spheroids found in meteorites, serving as important fossil records of the early solar system. In order to form chondrules, chondrule precursors must be heat…
Diffusive Versus Free-Streaming Cosmic Ray Transport in Molecular Clouds
Kedron Silsbee, Alexei V. Ivlev
Understanding the cosmic ray (CR) ionization rate is crucial in order to simulate the dynamics of, and interpret the chemical species observed in molecular clouds. Calculating the…
Producing Distant Planets by Mutual Scattering of Planetary Embryos
Kedron Silsbee, Scott Tremaine
It is likely that multiple bodies with masses between those of Mars and Earth ("planetary embryos") formed in the outer planetesimal disk of the solar system. Some of these were li…
