Thermal tides on a hot Jupiter
EPJ Web of Conferences, 2011 Following the linear analysis laid out by Gu & Ogilvie 2009 (hereafter GO09), we investigate the dynamical response of a non-synchronized hot Jupiter to stellar irradiation.

EVOLUTION OF OHMICALLY HEATED HOT JUPITERS [PDF]
The Astrophysical Journal, 2011 We present calculations of thermal evolution of Hot Jupiters with various masses and effective temperatures under Ohmic dissipation. The resulting evolutionary sequences show a clear tendency towards inflated radii for effective temperatures that give rise to significant ionization of alkali metals in the atmosphere, compatible with the trend of the ...

Starspots and spin-orbit alignment for Kepler cool host stars [PDF]
, 2012 The angle between the spin axis of the host star and the orbit of its planets (i.e., the stellar obliquity) is precious information about the formation and evolution of exoplanetary systems.

Tidal oscillations of rotating hot Jupiters [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We calculate small amplitude gravitational and thermal tides of uniformly rotating hot Jupiters composed of a nearly isentropic convective core and a geometrically thin radiative envelope. We treat the fluid in the convective core as a viscous fluid and solve linearized Navier–Stokes equations to obtain tidal responses of the ...

ATMOSPHERIC HEAT REDISTRIBUTION ON HOT JUPITERS [PDF]
The Astrophysical Journal, 2013 Infrared lightcurves of transiting hot Jupiters present a trend in which the atmospheres of the hottest planets are less efficient at redistributing the stellar energy absorbed on their daysides---and thus have a larger day-night temperature contrast---than colder planets.

Nondetection of Helium in the Hot Jupiter WASP-48b
The Astronomical Journal, 2023 Hot Jupiters orbiting extremely close to their host star may experience atmospheric escape due to the large amounts of high-energy radiation they receive. Understanding the conditions under which this occurs is critical, as atmospheric escape is believed

CIRCULATION AND DISSIPATION ON HOT JUPITERS [PDF]
The Astrophysical Journal, 2010 Many global circulation models predict supersonic zonal winds and large vertical shears in the atmospheres of short-period jovian exoplanets. Using linear analysis and nonlinear local simulations, we investigate hydrodynamic dissipation mechanisms to balance the thermal acceleration of these winds.

Atmospheric Circulation of Hot Jupiters: A Shallow Three-Dimensional Model
, 2009 Remote observing of exoplanetary atmospheres is now possible, offering us access to circulation regimes unlike any of the familiar Solar System cases. Atmospheric circulation models are being developed to study these new regimes but model validations and

The Aligned Orbit of the Eccentric Proto Hot Jupiter TOI-3362b
The Astrophysical Journal Letters, 2023 High-eccentricity tidal migration predicts the existence of highly eccentric proto hot Jupiters on the “tidal circularization track,” meaning that they might eventually become hot Jupiters, but that their migratory journey remains incomplete.

Superflares and “Hot-Jupiters” [PDF]
Symposium - 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.
