Hidden population of AM CVns in the SDSS
We present the latest results from a spectroscopic survey designed to uncover the hidden population of AM Canum Venaticorum (AM CVn) binaries in the photometric database of the... -
UVEX sources spectroscopic follow-up
We present the results of the first spectroscopic follow-up of 132 optically blue ultraviolet (UV)-excess sources selected from the UV-Excess Survey of the Northern Galactic... -
High proper-motion white dwarfs
We conducted a spectropolarimetric survey of 58 high proper-motion white dwarfs which achieved uncertainties of >~2kG in the H{alpha} line and >~5kG in the upper Balmer... -
SDSS-UKIDSS white dwarf-main sequence binaries
We develop optical and near-infrared colour-selection criteria based on the model colours of binaries consisting of a white dwarf and a main-sequence star. Using our... -
Variability of FBS blue stellar objects
A new method for combined calculations of magnitudes based on accurate measurements of POSS1 and POSS2 epoch plates is given. The photometric accuracy of various surveys and... -
Kepler compact pulsator candidates
We present results from the final 6 months of a survey to search for pulsations in white dwarfs (WDs) and hot subdwarf stars with the Kepler spacecraft. Spectroscopic... -
Candidate subdwarfs and white dwarfs
Photometry from the Two-Micron All-Sky Survey (2MASS), United States Naval Observatory CCD Astrograph Catalog (UCAC3) and SuperCosmos catalogues, together with proper motions... -
SDSS post-common envelope binaries. X
We present the first white dwarf mass distributions of a large and homogeneous sample of post-common envelope binaries (PCEBs) and wide white dwarf main-sequence (WDMS) binaries... -
Hot white dwarfs in GALEX-DR5
We present comprehensive catalogues of hot star candidates in the Milky Way (MW), selected from Galaxy Evolution Explorer (GALEX) far-UV (FUV; 1344-1786{AA}) and near-UV (NUV;... -
Kepler compact pulsator candidates
We present results from the first two quarters of a survey to search for pulsations in compact stellar objects with the Kepler spacecraft. The survey sample and the various... -
SDSS WD main-sequence binaries
We present a catalogue of 1602 white-dwarf-main-sequence (WDMS) binaries from the spectroscopic Sloan Digital Sky Survey Data Release 6 (SDSS DR6). Among these, we identify 440... -
Parameters of atmospheres of white dwarfs
It is possible to reliably identify white dwarfs (WDs) without recourse to spectra, instead using photometric and astrometric measurements to distinguish them from main-sequence... -
Binary evolution
Using Eggleton's stellar evolution code, we carry out 150 runs of Population I binary evolution calculations with the initial primary mass between 1 and 8 solar masses, the... -
IUE low-dispersion spectra of white dwarfs
We have produced an archive of the ultraviolet low-dispersion spectra for the full set of white dwarf stars observed with the International Ultraviolet Explorer (IUE) satellite... -
BVRIJHK photometry of cool white dwarfs
A detailed photometric and spectroscopic analysis of cool (T_eff_<~12000K) white dwarf stars is presented. The sample has been drawn from the Yale Parallax Catalog and from a... -
IUE echelle spectra of hot white dwarfs
This paper summarizes the results obtained from a comprehensive analysis of all of the SWP echelle spectra of the white dwarf stars contained in the IUE Final Archive. A total... -
Categorizing WDs with Gaia XP spectra and UMAP
White dwarfs (WDs) polluted by exoplanetary material provide the unprecedented opportunity to directly observe the interiors of exoplanets. However, spectroscopic surveys are... -
Spectrophotometric standard DA white dwarfs
We verified for photometric stability a set of DA white dwarfs with Hubble Space Telescope magnitudes from the near-ultraviolet to the near-infrared and ground-based... -
Massive white dwarfs in young star clusters
We have carried out a search for massive white dwarfs (WDs) in the direction of young open star clusters using the Gaia DR2 database. The aim of this survey was (1) to provide... -
Variable white dwarfs from Gaia & ZTF photometry
We present a novel method to detect variable astrophysical objects and transient phenomena using anomalous excess scatter in repeated measurements from public catalogs of Gaia...
