Prompt planetesimal formation beyond the snow line
Philip J. Armitage, Josh A. Eisner, Jacob B. Simon
We develop a simple model to predict the radial distribution of planetesimal formation. The model is based on the observed growth of dust to mm-sized particles, which drift radiall…
The Influence of Magnetic Field Geometry on the Formation of Close-in Exoplanets
Jacob B. Simon
Approximately half of Sun-like stars harbor exoplanets packed within a radius of ~0.3 AU, but the formation of these planets and why they form in only half of known systems are sti…
Turbulence, Transport and Waves in Ohmic Dead Zones
Daniel Gole, Jacob B. Simon, Stephen H. Lubow +1
We use local numerical simulations to study a vertically stratified accretion disk with a resistive mid-plane that damps magnetohydrodynamic (MHD) turbulence. This is an idealized…
Strongly magnetized accretion discs require poloidal flux
Greg Salvesen, Philip J. Armitage, Jacob B. Simon +1
Motivated by indirect observational evidence for strongly magnetized accretion discs around black holes, and the novel theoretical properties of such solutions, we investigate how…
