Journal ArticleDOI
Fast and scalable Gaussian process modeling with applications to astronomical time series
TL;DR: In this paper, the covariance function is expressed as a mixture of complex exponentials, without requiring evenly spaced observations or uniform noise, which can be used for probabilistic inference of stellar rotation periods, asteroseismic oscillation spectra and transiting planet parameters.

Ciardi,Ruth Angus,Ruth Angus,Laura Schaefer,David W. Latham,David Charbonneau,Charles Beichman,Jason D. Eastman,Nate McCrady,Robert A. Wittenmyer,Jason T. Wright +20 more
TL;DR: This paper reported observations of a white dwarf (WD 1145+017) being transited by at least one, and probably several, disintegrating planetesimals, with periods ranging from 4.5 hours to 4.9 hours.
Journal ArticleDOI
Fast and scalable Gaussian process modeling with applications to astronomical time series
TL;DR: A novel method for Gaussian processes modeling in one dimension where the computational requirements scale linearly with the size of the data set, and is fast and interpretable, with a range of potential applications within astronomical data analysis and beyond.
A Disintegrating Minor Planet Transiting a White Dwarf
Andrew Vanderburg,John Asher Johnson,Saul Rappaport,Allyson Bieryla,Jonathan Irwin,John Arban Lewis,David Charbonneau,David W. Latham,David R. Ciardi,Laura Schaefer,David M. Kipping,Ruth Angus,Jason D. Eastman,Jason T. Wright,Nate McCrady,Robert A. Wittenmyer,Patrick Dufour +16 more
TL;DR: Observations of a white dwarf being transited by at least one, and probably several, disintegrating planetesimals are reported, providing further evidence that the pollution of white dwarfs by heavy elements might originate from disrupted rocky bodies such as asteroids and minor planets.
Journal ArticleDOI
Calibrating gyrochronology using Kepler asteroseismic targets
TL;DR: In this article, the authors used rotation period measurements of 310 Kepler stars with asteroseismic ages, 50 stars from the Hyades and Coma Berenices clusters and 6 field stars (including the Sun) with precise age measurements to calibrate the gyrochronology relation.
