Composition Tracking for Collisions Between Differentiated Bodies in REBOUND
Noah Ferich, Anna C. Childs, Jason H. Steffen
Previous research suggests that impacts between planetary embryos and planetesimals during the late stages of planet formation can often determine the percentages of core and mantl…
Inclination instability of circumbinary planets
Stephen H. Lubow, Anna C. Childs, Rebecca G. Martin
We analyze a tilt instability of the orbit of an outer planet in a two planet circumbinary system that we recently reported. The binary is on an eccentric orbit and the inner circu…
Mergers of black hole binaries driven by misaligned circumbinary discs
Rebecca G. Martin, Stephen Lepp, Bing Zhang +2
With hydrodynamical simulations we examine the evolution of a highly misaligned circumbinary disc around a black hole binary including the effects of general relativity. We show th…
Composition constraints of the TRAPPIST-1 planets from their formation
Anna C. Childs, Cody Shakespeare, David R. Rice +2
We study the formation of the TRAPPIST-1 (T1) planets starting shortly after Moon-sized bodies form just exterior to the ice line. Our model includes mass growth from pebble accret…
Coplanar circumbinary planets can be unstable to large tilt oscillations in the presence of an inner polar planet
Anna C. Childs, Rebecca G. Martin, Stephen Lepp +2
Mutually misaligned circumbinary planets may form in a warped or broken gas disc or from later planet-planet interactions. With numerical simulations and analytic estimates we expl…
Misaligned circumbinary disks as efficient progenitors of interstellar asteroids
Anna C. Childs, Rebecca G. Martin
Gaseous circumbinary disks (CBDs) that are highly inclined to the binary orbit are commonly observed in nature. These disks harbor particles that can reach large mutual inclination…
