Hot Jupiters: Origins, Structure, Atmospheres
Journal of Geophysical Research: Planets, Volume 126, Issue 3, March 2021., 2021 Abstract
We provide a brief review of many aspects of the planetary physics of hot Jupiters. Our aim is to cover most of the major areas of current study while providing the reader with additional references for more detailed follow‐up. We first discuss giant planet formation and subsequent orbital evolution via disk‐driven torques or dynamical ...Jonathan J. Fortney, Rebekah I. Dawson, Thaddeus D.

Journal of Geophysical Research: Planets, Volume 126, Issue 2, February 2021., 2021 Abstract
The earliest atmospheres of rocky planets originate from extensive volatile release during magma ocean epochs that occur during assembly of the planet. These establish the initial distribution of the major volatile elements between different chemical reservoirs that subsequently evolve via geological cycles.Tim Lichtenberg, Dan J.
