On fragmentation of turbulent self-gravitating discs in the long cooling time regime
Ken Rice, Sergei Nayakshin
It has recently been suggested that in the presence of driven turbulence discs may be much less stable against gravitational collapse than their non turbulent analogs, due to stoch…
Precise Masses in the WASP-47 System
Andrew Vanderburg, Juliette C. Becker, Lars A. Buchhave +32
We present precise radial velocity observations of WASP-47, a star known to host a hot Jupiter, a distant Jovian companion, and, uniquely, two additional transiting planets in shor…
Three's Company: An additional non-transiting super-Earth in the bright HD 3167 system, and masses for all three planets
Jessie L. Christiansen, Andrew Vanderburg, Jennifer Burt +55
HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a…
Identifying and Analysing Protostellar Disc Fragments in Smoothed Particle Hydrodynamics Simulations
Cassandra Hall, Duncan Forgan, Ken Rice
We present a new method of identifying protostellar disc fragments in a simulation based on density derivatives, and analyse our data using this and the existing CLUMPFIND method,…
The Kepler-19 system: a thick-envelope super-Earth with two Neptune-mass companions characterized using Radial Velocities and Transit Timing Variations
Luca Malavolta, Luca Borsato, Valentina Granata +36
We report a detailed characterization of the Kepler-19 system. This star was previously known to host a transiting planet with a period of 9.29 days, a radius of 2.2 R and…
The VLT/NaCo large program to probe the occurrence of exoplanets and brown dwarfs at wide orbits. IV. Gravitational instability rarely forms wide, giant planets
A. Vigan, M. Bonavita, B. Biller +34
Understanding the formation and evolution of giant planets (1 ) at wide orbital separation (5 AU) is one of the goals of direct imaging. Over the past 15 years,…
