Capture of interstellar objects: a source of long-period comets
Tom Hands, Walter Dehnen
We simulate the passage through the Sun-Jupiter system of interstellar objects (ISOs) similar to 1I/`Oumuamua or 2I/Borisov. Capture of such objects is rare and overwhelmingly from…
The fate of planetesimal discs in young open clusters: implications for 1I/'Oumuamua, the Kuiper belt, the Oort cloud and more
Thomas Oliver Hands, Walter Dehnen, Amery Gration +2
We perform -body simulations of the early phases of open cluster evolution including a large population of planetesimals, initially arranged in Kuiper-belt like discs around eac…
A new class of Super-Earths formed from high-temperature condensates: HD219134 b, 55 Cnc e, WASP-47 e
Caroline Dorn, John H. D. Harrison, Amy Bonsor +1
We hypothesise that differences in the temperatures at which the rocky material condensed out of the nebula gas can lead to differences in the composition of key rocky species (e.g…
Breaking mean-motion resonances during Type I planet migration
T. O. Hands, R. D. Alexander
We present two-dimensional hydrodynamical simulations of pairs of planets migrating simultaneously in the Type I regime in a protoplanetary disc. Convergent migration naturally lea…
Understanding the assembly of Kepler's compact planetary systems
T. O. Hands, R. D. Alexander, W. Dehnen
The Kepler mission has recently discovered a number of exoplanetary systems, such as Kepler-11 and Kepler-32, in which ensembles of several planets are found in very closely packed…
