Reanalysis of SKR Source Crossed by Cassini: Loss Cone Electrons as a Secondary Source of Free Energy

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Saturn's Kilometric Radiation (SKR) is a powerful non‐thermal radio auroral emission produced by the Cyclotron Maser Instability (CMI), which generates waves close to the local cyclotron frequency in a highly magnetized plasma from mildly relativistic electrons.

Separating Super-puffs versus Hot Jupiters among Young Puffy Planets

open access: yesThe Astrophysical Journal
Discoveries of close-in young puffy ( R _p ≳ 6 R _⊕ ) planets raise the question of whether they are bona fide hot Jupiters or puffed-up Neptunes, potentially placing constraints on the formation location and timescale of hot Jupiters.

Saving Doomed Planets: Mass Loss and Angular Momentum Return Boost Hot Jupiter Survival Rates

open access: yesThe Astrophysical Journal
The existence of giant extrasolar planets on short-period orbits (“hot Jupiters”) challenges planet formation theories because such planets are difficult to form close to the star.

Hot Jupiter secondary eclipses measured by Kepler

open access: yesEPJ Web of Conferences, 2011
Hot-Jupiters are known to be dark in visible bandpasses, mainly because of the alkali metal absorption features. The outstanding quality of the Kepler mission photometry allows a detection (or non-detection upper limits on) giant planet secondary ...

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

open access: yes, 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.

Spin and Obliquity Evolution of Hot Jupiter Hosts from Resonance Locks

open access: yesThe Astrophysical Journal
When a hot Jupiter orbits a star whose effective temperature exceeds ∼6100 K, its orbit normal tends to be misaligned with the stellar spin axis. Cooler stars typically have smaller obliquities, which may have been damped by hot Jupiters in resonance ...

Hot Jupiters around M dwarfs

open access: yesEPJ Web of Conferences, 2013
The WFCAM Transit Survey (WTS) is a near-infrared transit survey running on the United Kingdom Infrared Telescope (UKIRT). We conduct Monte Carlo transit injection and detection simulations for short period (

Migration and Evolution of giant ExoPlanets (MEEP). I. Nine Newly Confirmed Hot Jupiters from the TESS Mission

open access: yesThe Astronomical Journal
Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery the mysteries surrounding their origins have remained. Here we present nine new hot Jupiters (TOI-1855 b, TOI-2107 b, TOI-2368 b, TOI-3321 b,
