New Dwarf novae in SDSS, GALEX and astrom. cat.
By cross-matching blue objects from the Sloan Digital Sky Survey with Galaxy Evolution Explorer and the astrometric catalogues USNO-B1.0, GSC2.3 and CMC14, 64 new dwarf nova... -
Optical monitoring from 2020-2022 of BL Lac
BL Lacertae is a key monitoring target of the 1.26m National Astronomical Observatory-Guangzhou University Infrared/Optical telescope. Within the monitored duration from 2020... -
Catalina Surveys periodic variable stars
We present ~47000 periodic variables found during the analysis of 5.4 million variable star candidates within a 20000deg^2^ region covered by the Catalina Surveys Data Release-1... -
The WIRED survey. II.
With the launch of the Wide-field Infrared Survey Explorer (WISE), a new era of detecting planetary debris and brown dwarfs (BDs) around white dwarfs (WDs) has begun with the... -
MegaCam survey of outer halo satellites. I.
We describe a deep, systematic imaging study of satellites in the outer halo of the Milky Way. Our sample consists of 58 stellar overdensities --i.e., substructures classified... -
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... -
SDSS wide double white dwarfs spectroscopy
We present observational constraints on the initial-final mass relation (IFMR) using wide double white dwarfs (DWDs). We identify 65 new candidate wide DWDs within the Sloan... -
M,L,T dwarfs fundamental parameters and SEDs
We combine optical, near-infrared, and mid-infrared spectra and photometry to construct expanded spectral energy distributions for 145 field age (>500 Myr) and 53 young... -
Imaging observations of iPTF 13ajg
We present imaging and spectroscopy of a hydrogen-poor superluminous supernova (SLSN) discovered by the intermediate Palomar Transient Factory, iPTF 13ajg. At a redshift of... -
Binary white dwarfs atmospheric parameters
We present a detailed spectroscopic analysis of 61 low-mass white dwarfs and provide precise atmospheric parameters, masses, and updated binary system parameters based on our... -
Extinction law in the Cep OB3b young cluster
We determine the extinction law through Cep OB3b, a young cluster of 3000 stars undergoing gas dispersal. The extinction is measured toward 76 background K giants identified... -
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... -
SDSS observations of Kuiper belt objects
Colors of trans-Neptunian objects (TNOs) are used to study the evolutionary processes of bodies in the outskirts of the solar system and to test theories regarding their origin.... -
Photometry monitoring of the SN PTF10vdl
The Palomar Transient Factory (PTF) is an optical wide-field variability survey carried out using a camera with a 7.8deg^2^ field of view mounted on the 48 inch Oschin Schmidt... -
Variability of low-mass stars in SDSS Stripe 82
We present a catalog of periodic stellar variability in the "Stripe 82" region of the Sloan Digital Sky Survey. After aggregating and re-calibrating catalog-level data from the... -
Photometry of SN 2009bb
Ultraviolet, optical, and near-infrared photometry and optical spectroscopy of the broad-lined Type Ic supernova (SN) 2009bb are presented, following the flux evolution from -10... -
Young intermediate-mass stars in W5
We present the results of a survey of young intermediate-mass stars (age<5Myr, 1.5M_{sun}<M*<=15M{sun}) in the W5 massive star-forming region. We use combined optical,... -
Faint UV standards from Swift, GALEX and SDSS
At present, the precision of deep ultraviolet photometry is somewhat limited by the dearth of faint ultraviolet standard stars. In an effort to improve this situation, we... -
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... -
Light curves of type Ia supernovae (CfA3)
We present multiband photometry of 185 type-Ia supernovae (SNe Ia), with over 11500 observations. These were acquired between 2001 and 2008 at the F. L. Whipple Observatory of...
