The ELM survey. VII. 15 new ELM white dwarf cand.
We present the discovery of 15 extremely low-mass (5<logg<7) white dwarf (WD) candidates, 9 of which are in ultra-compact double-degenerate binaries. Our targeted... -
The ELM survey. VI. 11 new ELM WD binaries
We present the discovery of 11 new double degenerate systems containing extremely low-mass white dwarfs (ELM WDs). Our radial velocity observations confirm that all of the... -
The ELM survey. V. White dwarf binaries
We present the discovery of 17 low-mass white dwarfs (WDs) in short-period (P<=1 day) binaries. Our sample includes four objects with remarkable logg=~5 surface gravities and... -
Carbon stars and DQ white dwarfs from SDSS-DR7+DR8
Among stars showing carbon molecular bands (C stars), the main-sequence dwarfs, likely in post-mass transfer binaries, are numerically dominant in the Galaxy. Via spectroscopic... -
DA white dwarfs infrared photometry
We present near- and mid-infrared photometry and spectroscopy from PAIRITEL, IRTF, and Spitzer of a metallicity-unbiased sample of 117 cool, hydrogen-atmosphere white dwarfs... -
Photometric catalogs for ECDF-S and CDF-N
We present an analysis of deep multiwavelength data for z~0.3-3 starburst galaxies selected by their 70um emission in the Extended-Chandra Deep Field-South and Extended Groth... -
Radial velocities of low-mass white dwarfs
We describe spectroscopic observations of 21 low-mass (<=0.45M_{sun}_) white dwarfs (WDs) from the Palomar-Green survey obtained over four years. We use both radial... -
The ELM survey. I. Low-mass white dwarfs
We analyze radial velocity observations of the 12 extremely low-mass (ELM), with <=0.25M_{sun}_, white dwarfs (WDs) in the MMT Hypervelocity Star Survey. Eleven of the twelve... -
White dwarfs from the Kiso survey
We present a spectroscopic analysis of white dwarfs found in the Kiso survey. Spectroscopic observations at high signal-to-noise ratio have been obtained for all DA and DB stars... -
Apparent velocity measurements of DA WDs
We measure apparent velocities (v_app_) of the H{alpha} and H{beta} Balmer line cores for 449 non-binary thin disk normal DA white dwarfs (WDs) using optical spectra taken for... -
Photoionization of H in strong magnetic fields
A recently developed computational scheme, based on the complex-rotation method combined with a mixed Slater-Landau basis expansion, has been applied to calculations of... -
Iron in hot DA white dwarfs
We present a study of the iron abundance pattern in hot, hydrogen-rich (DA) white dwarfs. The study is based on new and archival far-ultraviolet spectroscopy of a sample of... -
FUV-NUV observations of NGC 2808
We present a reanalysis of far-ultraviolet (FUV) observations of the globular cluster NGC 2808 obtained with the Hubble Space Telescope. These data were first analyzed by Brown... -
Catalog of white dwarfs in SDSS-DR1
We present the full spectroscopic white dwarf and hot subdwarf sample from the Sloan Digital Sky Survey (SDSS) First Data Release, DR1. We find 2551 white dwarf stars of various... -
7 white dwarfs systems J-, H-, and K-band spectroscopy
Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations... -
Gemini/GMOS transmission spectroscopy of WD 1856+534 b
WD1856+534b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD1856+534. Here, we report an optical transmission spectrum of WD1856+534b obtained from... -
Hot degenerates in the MCT survey. III.
We present optical spectra of 144 white dwarfs detected in the Montreal-Cambridge-Tololo colorimetric survey, including 120 DA, 12 DB, 4 DO, 1 DQ, and 7 DC stars. We also... -
LOAO BV-bands photometry and BOES RVs of WASP 0131+28
We report the first BV light curves and high-resolution spectra of the post-mass transfer binary star WASP0131+28 to study the absolute properties of extremely low-mass white... -
ZZ Ceti white dwarfs and candidates in Gaia survey
The Gaia satellite recently released parallax measurements for ~260000 high-confidence white dwarf candidates, allowing for precise measurements of their physical parameters. By... -
CALSPEC: WFC3 infrared grism spectrophotometry
The collections of spectral energy distributions (SEDs) in the Hubble Space Telescope (HST) CALSPEC database are augmented by 19 infrared (IR) SEDs from Wide Field Camera 3...
