Outward Migration of Super-Jupiters
Adam M. Dempsey, Diego J. Muñoz, Yoram Lithwick
Recent simulations show that giant planets of about one Jupiter mass migrate inward at a rate that differs from the Type II prediction. Here we show that at higher masses, planets…
Pileups and Migration Rates for Planets in Low Mass Disks
Adam M. Dempsey, Wing-Kit Lee, Yoram Lithwick
We investigate how planets interact with viscous accretion disks, in the limit that the disk is sufficiently low mass that the planet migrates more slowly than the disk material. I…
Long-Lived Eccentricities in Accretion Disks
Wing-Kit Lee, Adam M. Dempsey, Yoram Lithwick
Accretion disks can be eccentric: they support modes that are global and slowly precessing. But whether the modes remain trapped in the disk---and hence are long-lived---depe…
Ring Formation in Protoplanetary Disks Driven by an Eccentric Instability
Jiaru Li, Adam M. Dempsey, Hui Li +1
We find that, under certain conditions, protoplanetary disks may spontaneously generate multiple, concentric gas rings without an embedded planet through an eccentric cooling insta…
The Santa Barbara Binary-Disk Code Comparison
Paul C. Duffell, Alexander J. Dittmann, Daniel J. D'Orazio +13
We have performed numerical calculations of a binary interacting with a gas disk, using eleven different numerical methods and a standard binary-disk setup. The goal of this study…
Forming Gliese 876 Through Smooth Disk Migration
Adam M. Dempsey, Benjamin E. Nelson
We run a suite of dissipative N-body simulations to determine which regions of phase space for smooth disk migration are consistent with the GJ876 system, an M-dwarf hosting three…
