Occurrence rates of planets orbiting FGK stars: combining Kepler DR25, Gaia DR2, and Bayesian inference

DC Hsu, EB Ford, D Ragozzine… - The Astronomical …, 2019 - iopscience.iop.org
We characterize the occurrence rate of planets, ranging in size from 0.5 to 16 R⊕, orbiting
FGK stars with orbital periods from 0.5 to 500 days. Our analysis is based on results from …

Architectures of exoplanetary systems – I. A clustered forward model for exoplanetary systems around Kepler's FGK stars

MY He, EB Ford, D Ragozzine - Monthly Notices of the Royal …, 2019 - academic.oup.com
Observations of exoplanetary systems provide clues about the intrinsic distribution of
planetary systems, their architectures, and how they formed. We develop a forward …

Architectures of exoplanetary systems. III. Eccentricity and mutual inclination distributions of AMD-stable planetary systems

MY He, EB Ford, D Ragozzine… - The Astronomical …, 2020 - iopscience.iop.org
The angular momentum deficit (AMD) of a planetary system is a measure of its orbital
excitation and a predictor of long-term stability. We adopt the AMD-stability criterion to …

Occurrence rates of planets orbiting M Stars: applying ABC to Kepler DR25, Gaia DR2, and 2MASS data

DC Hsu, EB Ford, R Terrien - Monthly Notices of the Royal …, 2020 - academic.oup.com
We present robust planet occurrence rates for Kepler planet candidates around M stars for
planet radii Rp= 0.5–4 R⊕ and orbital periods P= 0.5–256 d using the approximate …

Improving the accuracy of planet occurrence rates from Kepler using approximate Bayesian computation
