Slow Cooling and Fast Reinflation for Hot Jupiters

no code implementations13 Jan 2021 Daniel P. Thorngren, Jonathan J. Fortney, Eric D. Lopez, Travis A. Berger, Daniel Huber

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.

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

2 code implementations29 May 2020 Travis A. Berger, Daniel Huber, Eric Gaidos, Jennifer L. van Saders, Lauren M. Weiss

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

1 code implementation19 May 2020 Kirsten Blancato, Melissa Ness, Daniel Huber, Yuxi Lu, Ruth Angus

Stellar variability is driven by a multitude of internal physical processes that depend on fundamental stellar properties.

The K2 Bright Star Survey I: Methodology and Data Release

1 code implementation19 Aug 2019 Benjamin J. S. Pope, Timothy R. White, Will M. Farr, Jie Yu, Michael Greklek-McKeon, Daniel Huber, Conny Aerts, Suzanne Aigrain, Timothy R. Bedding, Tabetha Boyajian, Orlagh L. Creevey, David W. Hogg

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

no code implementations18 Jan 2019 Torben Arentoft, Frank Grundahl, Timothy R. White, Ditte Slumstrup, Rasmus Handberg, Mikkel N. Lund, Karsten Brogaard, Mads F. Andersen, Victor Silva Aguirre, Chunguang Zhang, Xiaodian Chen, Zhengzhou Yan, Benjamin J. S.

Garcia, Licai Deng, Marc Hon, Dennis Stello, Uffe G. Jørgensen

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.

Asteroseismology of 16000 Kepler Red Giants: Global Oscillation Parameters, Masses, and Radii

2 code implementations13 Feb 2018 Jie Yu, Daniel Huber, Timothy R. Bedding, Dennis Stello, Marc Hon, Simon J. Murphy, Shourya Khanna

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.

Complexity of Discrete Energy Minimization Problems

no code implementations29 Jul 2016 Mengtian Li, Alexander Shekhovtsov, Daniel Huber

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
