Orbital Decay Candidates Reconsidered: WASP-4 b Is Not Decaying and Kepler-1658 b Is Not a Planet

The Planetary Science Journal
The fate of hot Jupiters is thought to be engulfment by their host stars, the outcome of tidal orbital decay. Transit timing has revealed a few systems with apparently shrinking orbital periods, but such signals can be mimicked by light travel-time ...

Exploring Warm Jupiter Migration Pathways with Eccentricities. I. Catalog of Uniform Keplerian Fits to Radial Velocities of 200 Warm Jupiters

The Astrophysical Journal Supplement Series
Giant planets are expected to predominantly form beyond the water-ice line and occasionally undergo inward migration. Unlike hot Jupiters, which can result from high-eccentricity tidal migration, warm Jupiters between 0.1 and 1 au (≈10–365 days) are in ...

From Misaligned Sub-Saturns to Aligned Brown Dwarfs: The Highest Mp/M* Systems Exhibit Low Obliquities, Even around Hot Stars

The Astrophysical Journal Letters
We present a pattern emerging from stellar obliquity measurements in single-star systems: planets with high planet-to-star mass ratios ( M _P / M _* ≥ 2 × 10 ^−3 )—such as super-Jupiters, brown dwarf companions, and M dwarfs hosting Jupiter-like planets ...

Age Analysis of Extrasolar Planets: Insight from Stellar Isochrone Models

The Astronomical Journal
There is growing evidence from stellar kinematics and galactic chemical evolution suggesting that giant planets ( M _P ≥ 0.3 M _J ) are relatively young compared to the most commonly occurring population of small planets ( M _P < 0.3 M _J ).

Hot Super Earths: Tidally Downsized hot jupiters? The hot jupiter around the metal poor star explained

, 2011
Recent Kepler observations revealed an unexpected abundance of "hot" Earth-size to Neptune-size planets in the inner ~0.02-0.2 AU from their parent stars. Another "oddity" of recent observations is the discovery of a hot jupiter planet around a very metal poor star of extragalactic origin.
