Age and colors of massive white dwarf stars
We present evolutionary calculations and colors for massive white dwarfs with oxygen-neon cores for masses between 1.06 and 1.28M_{sun}. The evolutionary stages computed cover... -
Sample of confirmed WDs in GSC-II survey
The GSC-II white dwarf survey was designed to identify faint and high proper motion objects, which we used to define a new and independent sample of cool white dwarfs. With this... -
3D-kinematics of white dwarfs from SPY project. II.
We present the kinematics of a sample of 398 DA white dwarfs from the SPY project (ESO SN Ia Progenitor surveY) and discuss kinematic criteria for distinguishing of thin-disk,... -
Isolated massive white dwarfs catalog
We present the catalogue of 112 massive isolated white dwarfs, both magnetic and nonmagnetic, with masses M>0.8M_{sun}_. Mass determinations and other parameters of white... -
Masses and radii of DA white dwarfs in SDSS DR1
We investigate the sample of 1175 new nonmagnetic DA white dwarfs with the effective temperatures T_eff_>=12000K, which were extracted from the Data Release 1 of the Sloan... -
White dwarfs 3D kinematics from SPY project
We present kinematics of a sample of 107 DA white dwarfs from the SPY project (ESO SN Ia Progenitor surveY) and discuss kinematic criteria for a distinction of thin disk, thick... -
Stellar Catalogue in the Chandra DFS
Stellar catalogues in five passbands (UBVRI) over an area of approximately 0.3{deg}^2^, comprising about 1200 objects, and in seven passbands (UBVRIJK) over approximately... -
ESO Imaging Survey. CDF-S point sources
This paper describes the methodology currently being implemented in the EIS pipeline for analysing optical/infrared multi-colour data. The aim is to identify different classes... -
UVES/VLT spectra of white dwarfs
We have started a large survey for radial velocity variations in white dwarfs (PI R. Napiwotzki) with the aim of finding close double degenerates, which could be precursor... -
DB white dwarfs from the Hamburg/ESO survey
We present an analysis of 40 cool helium-rich white dwarfs found in the Hamburg/ESO survey. They were selected for follow-up spectroscopy because of their U-B colour below... -
Faint Blue Stars near the South Galactic Pole
A search for faint blue stars conducted at the Observatories of Tonantzintla and Minnesota has yielded 8746 objects which are somewhat blue. The data file is organized into... -
Luyten's White Dwarf Catalogues
The catalogue includes all probable white dwarf and degenerate stars found in the Proper Motion and Faint Blue Star Surveys conducted by W.J. Luyten. The catalogue was... -
Revised and updated First Byurakan Survey (FBS)
Eleven lists of blue stellar objects (BSOs) were published in Astrophysics in 1990-1996, found in the First Byurakan Survey (FBS) low-dispersion spectroscopic plates. The... -
Spectroscopically Identified White Dwarfs
This compilation is an expanded and updated version to the second edition of the catalogue (Mc Cook and Sion 1984); it includes 1282 stars. Please refer to the introduction by... -
GD blue stars from Lowell proper motion survey
(no description available) Cone search capability for table II/299/gd (Summary catalog of the GD stars.) -
New white dwarf-open cluster associations
Open clusters (OCs) provide homogeneous samples of white dwarfs (WDs) with known distances, extinctions, and total ages. The unprecedented astrometric precision of Gaia allows... -
Gaia white dwarfs Classification
The latest Gaia data release in July 2022, DR3, in addition to the refinement of the astrometric and photometric parameters from DR2, added a number of important data products... -
Gaia stars with GALEX NUV excess
Accurate parallaxes from Gaia DR1 (TGAS) are combined with GALEX visual Nuv magnitudes to produce absolute MNUV magnitudes and an ultraviolet HR diagram for a large sample of... -
New Binary Systems from Data of Gaia DR2
The author describes the discovery of 4 new pairs of stars with almost identical proper motions and parallaxes (from Gaia DR2 data). Cone search capability for table... -
Full Evolutionary Sequences of Massive WDs
We explore the evolution of hydrogen-rich and hydrogen-deficient white dwarf stars with masses between 1.012 and 1.307M_{sun}, and initial metallicity of Z=0.02. These sequences...
