Tidal Response and Shape of Hot Jupiters [PDF]
The Astrophysical Journal, 2021 Abstract We study the response of hot Jupiters to a static tidal perturbation using the concentric MacLaurin spheroid method. For strongly irradiated planets, we first performed radiative transfer calculations to relate the planet’s equilibrium temperature, T eq, to its interior entropy.

Three Warm Jupiters around Solar-analog Stars Detected with TESS
The Astronomical Journal, 2023 We report the discovery and characterization of three giant exoplanets orbiting solar-analog stars, detected by the TESS space mission and confirmed through ground-based photometry and radial velocity measurements taken at La Silla observatory with FEROS.

Re-evaluating hot Jupiter WASP-12b: An update
EPJ Web of Conferences, 2013 The hot Jupiter WASP-12b is one of the largest, hottest, and best-studied extrasolar planets. We revisit our recent analysis of WASP-12b's emission spectrum in light of near-infrared spectroscopic measurements which have been claimed to support either a ...

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.

Radiative equilibrium models of “hot Jupiters” [PDF]
Symposium - International Astronomical Union, 2004 We present an extension of our equilibrium model, initially applied to 51 Peg b (Goukenleuque et al. 2000), to other irradiated extrasolar planets with different orbital distances (up to 1 AU). The model yields the mean atmospheric thermal structure and predicts the reflected spectral flux as well as the thermal flux emerging from such planets, in the ...

The TESS Grand Unified Hot Jupiter Survey. II. Twenty New Giant Planets
The Astrophysical Journal Supplement Series, 2023 NASA’s Transiting Exoplanet Survey Satellite (TESS) mission promises to improve our understanding of hot Jupiters by providing an all-sky, magnitude-limited sample of transiting hot Jupiters suitable for population studies.

TRANSITIONS IN THE CLOUD COMPOSITION OF HOT JUPITERS [PDF]
The Astrophysical Journal, 2016 ABSTRACT Over a large range of equilibrium temperatures, clouds shape the transmission spectrum of hot Jupiter atmospheres, yet their composition remains unknown. Recent observations show that the Kepler light curves of some hot Jupiters are asymmetric: for the hottest planets, the light curve peaks before secondary eclipse, whereas for ...

, 2021 The properties of a planetary system may be influenced by properties of the host star, such as its birth environment or age. Recently, a link has been found between a star's local phase space density in the Galaxy and the presence of a hot Jupiter: hot Jupiters are preferentially found around stars with higher local phase space densities.

The Astronomical JournalCharacterizing outer companions to hot Jupiters plays a crucial role in deciphering their origins. We present the discovery of a long-period giant planet, HD 118203 c ( ${m}_{c}={11.79}_{-0.63}^{+0.69}\ {M}_{{\rm{J}}}$ , ${a}_{c}={6.28}_{-0.11}^{+0.10 ...
