The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-spaceExpand

A Gaia Data Release 2 catalogue of white dwarfs and a comparison with SDSS
We present a catalogue of white dwarf candidates selected from the second data release of Gaia (DR2). We used a sample of spectroscopically confirmed white dwarfs from the Sloan Digital Sky SurveyExpand

The second data release of the INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS DR2)
The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800 deg2 imaging survey covering Galactic latitudes |b| < 5° and longitudes l = 30°–215° in the r, i, and Hα filtersExpand

White Dwarf Rotation as a Function of Mass and a Dichotomy of Mode Line Widths: Kepler Observations of 27 Pulsating DA White Dwarfs through K2 Campaign 8
We present photometry and spectroscopy for 27 pulsating hydrogen-atmosphere white dwarfs (DAVs; a.k.a. ZZ Ceti stars) observed by the Kepler space telescope up to K2 Campaign 8, an extensiveExpand

Fundamental parameter accuracy of DA and DB white dwarfs in Gaia Data Release 2
We report on a comparison of spectroscopic analyses for hydrogen (DA) and helium atmosphere (DB) white dwarfs with Gaia Data Release 2 (DR2) parallaxes and photometry. We assume a reddening law and aExpand

A photometric selection of white dwarf candidates in Sloan Digital Sky Survey Data Release 10
We present a method which uses cuts in colour–colour and reduced proper motion–colour space to select white dwarfs without the recourse to spectroscopy while allowing an adjustable compromise betweenExpand

Core crystallization and pile-up in the cooling sequence of evolving white dwarfs
White dwarfs are stellar embers depleted of nuclear energy sources that cool over billions of years1. These stars, which are supported by electron degeneracy pressure, reach densities of 107 gramsExpand

The population of hot subdwarf stars studied with Gaia. II. The Gaia DR2 catalogue of hot subluminous stars
Based on data from the ESA Gaia Data Release 2 (DR2) and several ground-based, multi-band photometry surveys we compiled an all-sky catalogue of $39\,800$ hot subluminous star candidates selected inExpand
