The steady-state flow pattern past gravitating bodies
C. W. Ormel
Gravitating bodies significantly alter the flow pattern (density and velocity) of the gas that attempts to stream past. Still, small protoplanets in the Mars--super-Earth range can…
Breaking through: The effects of a velocity distribution on barriers to dust growth
Fredrik Windmark, Til Birnstiel, Chris Ormel +1
It is unknown how far dust growth can proceed by coagulation. Obstacles to collisional growth are the fragmentation and bouncing barriers. However, in all previous simulations of t…
Migration rates of planets due to scattering of planetesimals
Chris Ormel, Shigeru Ida, Hidekazu Tanaka
Planets migrate due to the recoil they experience from scattering solid (planetesimal) bodies. To first order, the torques exerted by the interior and exterior disks cancel, analog…
Rapid Formation of Saturn after Jupiter Completion
Hiroshi Kobayashi, Chris W. Ormel, Shigeru Ida
We have investigated Saturn's core formation at a radial pressure maximum in a protoplanetary disk, which is created by gap opening by Jupiter. A core formed via planetesimal accre…
