The Epoch of Giant Planet Migration Planet Search Program. II. A Young Hot Jupiter Candidate around the AB Dor Member HS Psc [PDF]

The Astronomical Journal
We report the discovery of a hot Jupiter candidate orbiting HS Psc, a K7 (≈0.7 M _⊙ ) member of the ≈130 Myr AB Doradus moving group. Using radial velocities over 4 yr from the Habitable-zone Planet Finder spectrograph at the Hobby–Eberly Telescope, we ...

Aligned Stellar Obliquities for Two Hot Jupiter-hosting M Dwarfs Revealed by MAROON-X: Implications for Hot Jupiter Formation [PDF]

The Astronomical Journal
Hot Jupiters (HJs) are 2–3× less common around M dwarfs than around AFGK stars, suggesting that HJs may form and/or migrate via distinct pathways around different types of stars.

Hot Jupiters around M dwarfs

EPJ 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 (

Hot Jupiters Are Asynchronous Rotators

The Astrophysical Journal Letters
Hot Jupiters are typically assumed to be synchronously rotating, from tidal locking. Their thermally driven atmospheric winds experience Lorentz drag on the planetary magnetic field anchored at depth.

Constraining Young Hot Jupiter Occurrence Rate in Stellar Associations Using 2-min Cadence TESS Data

Universe, 2023
The characterization of young planet distribution is essential for our understanding of the early evolution of exoplanets. Here we conduct a systematic search for young planets from young open clusters and associations using the 2-min cadence TESS survey

A High-Eccentricity Warm Jupiter Orbiting TOI-4127

The Astronomical Journal, 2023
We report the discovery of TOI-4127 b, which is a transiting, Jupiter-sized exoplanet on a long-period ( $P={56.39879}_{-0.00010}^{+0.00010}$ days) and a high-eccentricity orbit around a late F-type dwarf star.

Tidal Quality of the Hot Jupiter WASP-12b

Universe, 2022
WASP-12b stands out among the planets of its class of hot Jupiters because of the observed fast orbital decay attributed to tidal dissipation. The measured rate of the orbital period change is P⋅orb=−29±3ms/yr= −(9.2±1.0)×10−10s/s.
