Slow Cooling and Fast Reinflation for Hot Jupiters
In this work, we examine the observed population of hot Jupiters to see if they grow as their parent stars brighten along the main sequence.

The Occurrence of Rocky Habitable Zone Planets Around Solar-Like Stars from Kepler Data
We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties.

The Gaia-Kepler Stellar Properties Catalog. II. Planet Radius Demographics as a Function of Stellar Mass and Age
We measure the stellar mass dependence of the planet radius valley to be $d \log R_{\mathrm{p}}$/$d \log M_\star = 0. 26^{+0. 21}_{-0. 16}$, consistent with the slope predicted by a planet mass dependence on stellar mass ($0. 24-0. 35$) and core-powered mass-loss (0. 33).

Data-driven derivation of stellar properties from photometric time series data using convolutional neural networks
Stellar variability is driven by a multitude of internal physical processes that depend on fundamental stellar properties.

The Gaia-Kepler Stellar Properties Catalog. I. Homogeneous Fundamental Properties for 186,301 Kepler Stars
An accurate and precise Kepler Stellar Properties Catalog is essential for the interpretation of the Kepler exoplanet survey results.

The K2 Bright Star Survey I: Methodology and Data Release
While the Kepler Mission was designed to look at tens of thousands of faint stars (V > 12), brighter stars that saturated the detector are important because they can be and have been observed very accurately by other instruments.

Asteroseismology of the Hyades red giant and planet host epsilon Tauri
Using asteroseismic techniques combined with other methods, we aim to derive physical parameters and the evolutionary stage for the planet hosting star epsilon Tau, which is one of the four red giants located in the Hyades.

Revised Radii of Kepler Stars and Planets Using Gaia Data Release 2
Using the revised stellar radii, we recalculate the radii for 2123 confirmed and 1922 candidate exoplanets.

Aldebaran b's temperate past uncovered in planet search data
The nearby red giant Aldebaran is known to host a gas giant planetary companion from decades of ground-based spectroscopic radial velocity measurements.

Asteroseismology of 16000 Kepler Red Giants: Global Oscillation Parameters, Masses, and Radii
Thanks to the large red giant sample, we confirm that red-giant-branch (RGB) and helium-core-burning (HeB) stars collectively differ in the distribution of oscillation amplitude, granulation power, and width of power excess, which is mainly due to the mass difference.

Planetary Candidates Observed by Kepler. VIII. A Fully Automated Catalog With Measured Completeness and Reliability Based on Data Release 25
For orbital periods less than 100 days the Robovetter completeness (the fraction of simulated transits that are determined to be planet candidates) across all observed stars is greater than 85%.

Guaranteed Parameter Estimation for Discrete Energy Minimization
In this work, we propose a method to overcome this limitation through exploiting the properties of the joint problem of training time inference and learning.
Complexity of Discrete Energy Minimization Problems
Specifically, we show that general energy minimization, even in the 2-label pairwise case, and planar energy minimization with three or more labels are exp-APX-complete.
Photometry of Very Bright Stars with Kepler and K2 Smear Data
High-precision time series photometry with the Kepler satellite has been crucial to our understanding both of exoplanets, and via asteroseismology, of stellar physics.
