Multiple-Planet Scattering and the Origin of Hot Jupiters

open access: yes, 2011
Exoplanets show a pile-up of Jupiter-size planets in orbits with a 3-day period. A fraction of these hot Jupiters have retrograde orbits with respect to the parent star's rotation.

Hot Jupiters and the evolution of stellar angular momentum [PDF]

open access: yes, 2009
Giant planets orbiting main-sequence stars closer than 0.1 AU are called hot Jupiters. They interact with their stars affecting their angular momentum. Recent observations provide suggestive evidence of excess angular momentum in stars with hot Jupiters ...

Superflares and “Hot-Jupiters” [PDF]

open access: yesSymposium - International Astronomical Union, 2004
Schaefer, King & Deliyannis (2000) reported the discovery of powerful stellar flares on single, solar-type stars. The outbursts on these F8-G8 stars were 102–107 times more powerful than the largest solar flares. The observed properties are similar to the magnetic reconnection driven events of RS CVn binaries.

New Clues to Reveal Origins of Hot- and Warm-Jupiter: Mutual Occurrence Rate of Hot Jupiter,Warm Jupiter and Cold Jupiter [PDF]

open access: yes, 2021
Abstract Many works based on the correlations between the occurrence rate of various giant planets and stellar properties of their hosts have provided clues revealing planetary formation processes. However, few researches have focused on the mutual occurrence rate of different type of planets and their dependency upon the stellar properties ...

Thermal tides in rotating hot Jupiters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
ABSTRACT We calculate tidal torque due to semidiurnal thermal tides in rotating hot Jupiters, taking account of the effects of radiative cooling in the envelope and of the planets rotation on the tidal responses. We use a simple Jovian model composed of a nearly isentropic convective core and a thin radiative envelope.

On the Tidal Dissipation of Obliquity

open access: yes, 2013
We investigate tidal dissipation of obliquity in hot Jupiters. Assuming an initial random orientation of obliquity and parameters relevant to the observed population, the obliquity of hot Jupiters does not evolve to purely aligned systems.

Hot Jupiters in Binary Star Systems [PDF]

open access: yesThe Astrophysical Journal, 2007
Radial velocity surveys find Jupiter mass planets with semi-major axes a less than 0.1 AU around ~1% of solar-type stars; counting planets with $a$ as large as 5 AU, the fraction of stars having planets reaches ~ 10% {Marcy,Butler}. An examination of the distribution of semi-major axes shows that there is a clear excess of planets with orbital periods ...

Reinflation of Warm and Hot Jupiters [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract Understanding the anomalous radii of many transiting hot gas-giant planets is a fundamental problem of planetary science. Recent detections of reinflated warm Jupiters orbiting post-main-sequence stars and the reinflation of hot Jupiters while their host stars evolve on the main sequence may help constrain models for the ...

The formation and habitability of terrestrial planets in the presence of hot jupiters

open access: yes, 2004
`Hot jupiters,' giant planets with orbits very close to their parent stars, are thought to form farther away and migrate inward via interactions with a massive gas disk.
