Magnetic field strengths of hot Jupiters from signals of star–planet interactions [PDF]
Nature Astronomy, 2019 Evidence of star–planet interactions in the form of planet-modulated chromospheric emission has been noted for a number of hot Jupiters. Magnetic star–planet interactions involve the release of energy stored in the stellar and planetary magnetic fields ...

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 ...

Transit Signatures of Inhomogeneous Clouds on Hot Jupiters: Insights from Microphysical Cloud Modeling [PDF]
Astrophysical Journal, 2019 We determine the observability in transmission of inhomogeneous cloud cover on the limbs of hot Jupiters through post-processing a general circulation model to include cloud distributions computed using a cloud microphysics model.

Hot Jupiters Are Destroyed by Tides While Their Host Stars Are on the Main Sequence [PDF]
Astronomical Journal, 2019 While cooler giant planets are often observed with nonzero eccentricities, the short-period circular orbits of hot Jupiters suggest that they lose orbital energy and angular momentum due to tidal interactions with their host stars. However, orbital decay

, 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 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.

Advanced Science, EarlyView.Crystal‐orientation controlled hot‐rolling strategy creates Mg‐Ta immiscible composites featuring mechanically interlocked in situ formed interfaces (80.5 MPa bond strength) and excellent tensile properties (340–395 MPa UTS). Systematic multiscale investigations reveal a serration‐size‐dependent bonding mechanism and a three‐stage interfacial evolution
