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 ).

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 ...

Formation of Ultra-short-period Planets in Hot Jupiter Systems: Application to WASP-47

The Astrophysical Journal Letters
The WASP-47 system is notable as the first known system hosting both inner and outer low-mass planetary companions around a hot Jupiter, with an ultra-short-period (USP) planet as the innermost planetary companion.

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 ...
