Stellar sp. libraries in Opt-NIR. I. UVES-POP
We present reprocessed flux-calibrated spectra of 406 stars from the UVES-POP stellar library in the wavelength range 320-1025nm, which can be used for stellar population... -
A statistical analysis of Galactic radio SNRs
We present a revised table of 390 Galactic radio supernova remnants (SNRs) and their basic parameters. Statistical analyses are performed on SNR diameters, ages, spectral... -
Low-mass companions to KOIs observed with APOGEE
We report the characterization of 28 low-mass (0.02M_{sun}<=M_2<=0.25M_{sun}_) companions to Kepler objects of interest (KOIs), eight of which were previously designated... -
Dipper stars from TESS & Gaia
Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10%-50%, likely induced by... -
Stellar population parameters from LAMOST DR7
We first derive the stellar population properties: age and metallicity for ~43000 low redshift galaxies in the DR7 of the Large Sky Area Multi-Object Fiber Spectroscopic... -
Membership and rotational data for clusters
The period versus mass diagrams (i.e., rotational sequences) of open clusters provide crucial constraints for angular momentum evolution studies. However, their memberships are... -
Compilation of W UMa stars
We present a statistical study of the largest bibliographic compilation of stellar and orbital parameters of W UMa stars derived by light-curve synthesis with Roche models. The... -
Ages of field stars from white dwarf comp. in Gaia
We analyze 4050 wide binary star systems involving a white dwarf (WD) and usually a main-sequence (MS) star, drawn from the large sample assembled by Tian+ (2020, J/ApJS/246/4).... -
High-resolution spectroscopy of TESS stars
Accurate atmospheric parameters and chemical composition of stars play a vital role in characterizing physical parameters of exoplanetary systems and understanding of their... -
Opt. photometry of SMUDGes ultra-diffuse galaxies
We present the first systematic study of the stellar populations of ultra-diffuse galaxies (UDGs) in the field, integrating the large area search and characterization of UDGs by... -
YSOs in LDN 1641 with Hectochelle spectra
We investigate the young stellar objects (YSOs) in the Lynds 1641 (L1641) cloud using multi-wavelength data including Spitzer, WISE, the Two Micron All Sky Survey, and XMM... -
APOKASC catalog of KIC dwarfs and subgiants
We present the first APOKASC catalog of spectroscopic and asteroseismic data for dwarfs and subgiants. Asteroseismic data for our sample of 415 objects have been obtained by the... -
BANYAN. VII. Candidate YMG members from BASS
We present the results of a near-infrared (NIR) spectroscopic follow-up survey of 182 M4-L7 low-mass stars and brown dwarfs (BDs) from the BANYAN All-Sky Survey (BASS) for... -
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... -
PMS stars in the Cepheus flare region
We present results of optical spectroscopic and BVR_C_I_C_ photometric observations of 77 pre-main-sequence (PMS) stars in the Cepheus flare region. A total of 64 of these are... -
HD 76151 and Sun near-infrared spectroscopy
Determining the physical nature of a star requires precise knowledge of its stellar atmospheric parameters, including effective temperature, surface gravity, and metallicity.... -
Binary fraction of young stars in ~0.4pc of the GC
We present the first estimate of the intrinsic binary fraction of young stars across the central ~0.4pc surrounding the supermassive black hole (SMBH) at the Milky Way Galactic... -
Red dwarfs, Xray, UV, and CaII
The vast majority of stars in the nearby stellar neighborhood are M dwarfs. Their low masses and luminosities result in slow rates of nuclear evolution and minimal changes to... -
Improved stellar parameters of Kepler RGB stars
This paper reports the estimated stellar parameters of 1153 Kepler red giant branch stars determined with asteroseismic modeling. We use radial-mode oscillation frequencies,... -
A search for stellar siblings of TOI-251b syst.
Young planets (<1Gyr) are helpful for studying the physical processes occurring at the early stage of planet evolution. TOI-251 b is a recently discovered sub-Neptune...
