Title: The hot Jupiter period-mass distribution as a signature of in situ formation
Authors: Elizabeth Bailey, Konstantin Batygin
First Author’s Institution: California Institute of Technology
Status: Published in ApJL
To fully understand how and where planets can form, astronomers must look to the extremes. One of the most exotic discoveries in exoplanet research has been of a class of planets known as hot Jupiters. These are gaseous worlds, hundreds of times the mass of the Earth, that orbit their host stars in mere days. Given the major role that Jupiter had in shaping our solar system, it is crucial to understand how gas-giant planets form in a variety of environments.
How to Build a Jupiter
The formation of a Jupiter-sized world is thought to be a two-step process. First, material in the protoplanetary disk conglomerates to form a solid core. If this core grows larger than about 10x the mass of the ...
