DISCERNING EXOPLANET MIGRATION MODELS USING SPIN-ORBIT MEASUREMENTS [PDF]

Astrophysical Journal, 2011
We investigate the current sample of exoplanet spin-orbit measurements to determine whether a dominant planet migration channel can be identified, and at what confidence.

The Exoplanet Radius Valley from Gas-driven Planet Migration and Breaking of Resonant Chains

Astrophysical Journal Letters, 2022
The size frequency distribution of exoplanet radii between 1 and 4R ⊕ is bimodal with peaks at ∼1.4 R ⊕ and ∼2.4 R ⊕, and a valley at ∼1.8 R ⊕. This radius valley separates two classes of planets—usually referred to as “super-Earths” and “mini-Neptunes ...

The Exoplanet Orbit Database [PDF]

Publications of the Astronomical Society of the Pacific, 2011
We present a database of well-determined orbital parameters of exoplanets, and their host stars’ properties. This database comprises spectroscopic orbital elements measured for 427 planets orbiting 363 stars from radial velocity and transit measurements ...

Quantifying Orbital Migration from Exoplanet Statistics and Host Metallicities

Astrophysical Journal, 2005
We investigate how the statistical distribution of extrasolar planets may be combined with knowledge of the host stars' metallicity to yield constraints on the migration histories of gas giant planets. At any radius, planets that barely manage to form around the lowest metallicity stars accrete their envelopes just as the gas disk is being dissipated ...
