Hot-Jupiters and hot-Neptunes: A common origin? [PDF]
Astronomy & Astrophysics, 2005 We compare evolutionary models for close-in exoplanets coupling irradiation and evaporation due respectively to the thermal and high energy flux of the parent star with observations of recently discovered new transiting planets. The models provide an overall good agreement with observations, although at the very limit of the quoted error bars of OGLE ...

The Astronomical Journal, 2022 We present an estimate of the occurrence rate of hot Jupiters (7 R _⊕ ≤ R _p ≤ 2 R _J , 0.8 ≤ P _b ≤ 10 days) around early-type M dwarfs based on stars observed by the Transiting Exoplanet Survey Satellite (TESS) during its primary mission.

Absence of a metallicity effect for ultra-short-period planets [PDF]
, 2017 Ultra-short-period (USP) planets are a newly recognized class of planets with periods shorter than one day and radii smaller than about 2 Earth radii.

The Period Distribution of Hot Jupiters Is Not Dependent on Host Star Metallicity
The Astrophysical Journal Letters, 2023 The probability that a Sun-like star has a close-orbiting giant planet (period ≲1 yr) increases with stellar metallicity. Previous work provided evidence that the period distribution of close-orbiting giant planets is also linked to metallicity, hinting ...

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.

INFLATING HOT JUPITERS WITH OHMIC DISSIPATION [PDF]
The Astrophysical Journal, 2010 We present a new, magnetohydrodynamic mechanism for inflation of close-in giant extrasolar planets. The idea behind the mechanism is that current, which is induced through interaction of atmospheric winds and the planetary magnetic field, results in significant Ohmic dissipation of energy in the interior.

The Influence of Host Star Spectral Type on Ultra-Hot Jupiter Atmospheres [PDF]
, 2019 Ultra-hot Jupiters are the most highly irradiated gas giant planets, with equilibrium temperatures from 2000 to over 4000 K. Ultra-hot Jupiters are amenable to characterization due to their high temperatures, inflated radii, and short periods, but their ...

A short-period censor of sub-Jupiter mass exoplanets with low density [PDF]
, 2010 Despite the existence of many short-period hot Jupiters, there is not one hot Neptune with an orbital period less than 2.5 days. Here we discuss a cluster analysis of the currently known 106 transiting exoplanets to investigate a possible explanation for

A Massive Hot Jupiter Orbiting a Metal-rich Early M Star Discovered in the TESS Full-frame Images
The Astronomical Journal, 2023 Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these extreme systems has remained under debate for decades. With the help of the TESS mission and ground-
