Bright white dwarfs for high-speed photometry
The upcoming NASA Transiting Exoplanet Survey Satellite (TESS) will obtain space-based uninterrupted light curves for a large sample of bright white dwarfs distributed across... -
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... -
High proper motion stars in SA 94
We have applied the astrometric techniques devised by Murray (1986MNRAS.223..649M) for analysis of 48-inch Schmidt photographic data to SuperCOSMOS scans of UK Schmidt plates... -
Hot subdwarf stars with Gaia DR2 and LAMOST DR7 data
Based on the Gaia DR2 catalog of hot subdwarf star candidates, we identified 1587 hot subdwarf stars with spectra in LAMOST DR7. We present atmospheric parameters for these... -
NIR proper motion survey using 2MASS
We have conducted a 4030deg^2^ near-infrared proper motion survey using multi-epoch data from the Two Micron All-Sky Survey (2MASS). We find 2778 proper motion candidates, 647... -
Hot subdwarf stars from LAMOST DR5 & Gaia DR2
Combing Gaia DR2 with LAMOST DR5, we spectroscopically identified 924 hot subdwarf stars, among which 32 stars exhibit strong double-lined composite spectra. We measured the... -
Candidate halo wide binaries
We present an improved catalog of halo wide binaries compiled from an extensive literature search. Most of our binaries stem from the common proper motion binary catalogs by... -
UBVRI photometry of NLTT stars
UBVRI photometry is presented for a sample of 1656 southern stars, including 1211, that were previously not measured, drawn from the NLTT (Luyten, 1979; catalogue I/98)... -
High proper-motion M-type stars spectroscopic obs.
Large numbers of low-to-medium-resolution spectra of M-type dwarf stars from both the local Galactic disk and halo are available from various surveys. In order to fully exploit... -
Discoveries from the NEOWISE proper motion survey
We present low-resolution near-infrared spectra of discoveries from an all-sky proper motion search conducted using multi-epoch data from the Wide-field Infrared Survey... -
The solar neighborhood. XLII. New nearby subdwarfs
Parallaxes, proper motions, and optical photometry are presented for 51 systems consisting of 37 cool subdwarf and 14 additional high proper motion systems. Thirty-seven systems... -
Astrometry&photometry for late-type dwarfs&subdwarfs
New, updated, and/or revised CCD parallaxes determined with the Strand Astrometric Reflector at the Naval Observatory Flagstaff Station are presented. Included are results for... -
Catalogue of hot subdwarf stars DR2
In light of substantial new discoveries of hot subdwarfs by ongoing spectroscopic surveys and the availability of new all-sky data from ground-based photometric surveys and the... -
Gaia 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 have compiled an all-sky catalogue of 39800 hot subluminous star... -
Catalog of hot subdwarf stars
In preparation for the upcoming all-sky data releases of the Gaia mission we compiled a catalog of known hot subdwarf stars and candidates drawn from the literature and yet... -
Parallaxes of 10 ultracool subdwarfs
We measure absolute trigonometric parallaxes and proper motions with respect to many background galaxies for a sample of ten ultracool subdwarfs. Observations were taken in the... -
Hot subdwarfs proper motions
We report on first results from an ongoing program to measure and analyze proper motions for hot subdwarf and white dwarf stars, with the aim of determining to which stellar... -
Candidate halo dark matter
The Milky Way galaxy contains a large, spherical component which is believed to harbor a substantial amount of unseen matter. Recent observations indirectly suggest that as much... -
M-subdwarf research. II. Catalog of ~3000 subdwarfs
We applied the revised M subdwarf classification criteria discussed in Zhang+ 2019, J/ApJS/240/31 (Paper I) to Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)... -
SDSS4 confirmed white dwarfs catalog
We present a catalog of 9316 spectroscopically confirmed white dwarfs from the Sloan Digital Sky Survey Data Release 4. We have selected the stars through photometric cuts and...
