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

, 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 ...

A Uniform Search for Nearby Planetary Companions to Hot Jupiters in TESS Data Reveals Hot Jupiters Are Still Lonely [PDF]

, 2023
We present the results of a uniform search for additional planets around all stars with confirmed hot Jupiters observed by the Transiting Exoplanet Survey Satellite (TESS) in its Cycle 1 survey of the southern ecliptic hemisphere.

Inflation of migrated hot Jupiters

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT The observed low densities of gas giant planets with a high equilibrium temperature (hot Jupiters) can be simulated in models when a fraction of the surface radiation is deposited deeper in the interior. Meanwhile, migration theories suggest that hot Jupiters formed further away from their host star and migrated inward.

Exoplanets: Atmospheres of Hot Jupiters [PDF]

, 2019
The history of exoplanetary atmospheres studies is strongly based on the observations and investigations of the gaseous envelopes of hot Jupiters—exoplanet gas giants that have masses comparable to the mass of Jupiter and orbital semi-major axes shorter ...

Thermosphere and exosphere of hot Jupiters [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractHere we describe the observations and the resulting constraints on the upper atmosphere (thermosphere and exosphere) of hot Jupiters. In particular, observations and theoretical modeling of hot-Jupiter evaporation are described. The observations allowed the discovery that the planet orbiting HD209458 has an extended atmosphere of escaping ...

Two New HATNet Hot Jupiters around A Stars and the First Glimpse at the Occurrence Rate of Hot Jupiters from TESS [PDF]

, 2019
peer reviewedWide-field surveys for transiting planets are well suited to searching diverse stellar populations, enabling a better understanding of the link between the properties of planets and their parent stars.

OHMIC DISSIPATION IN THE ATMOSPHERES OF HOT JUPITERS [PDF]

The Astrophysical Journal, 2010
Hot Jupiter atmospheres exhibit fast, weakly-ionized winds. The interaction of these winds with the planetary magnetic field generates drag on the winds and leads to ohmic dissipation of the induced electric currents. We study the magnitude of ohmic dissipation in representative, three-dimensional atmospheric circulation models of the hot Jupiter HD ...
