Spectral types of OB stars <200Myr from Gaia DR3
The structure and evolution of the spiral arms of the Milky Way have long been an important yet controversial issue. The wide age range of OB-type stars, coupled with the large... -
Catalog of 519 high velocity stars (HiVels)
Utilizing astrometric parameters sourced from Gaia Data Release 3 and radial velocities obtained from various spectroscopic surveys, we identify 519 high-velocity stars (HiVels)... -
The APO-K2 Catalog. I. 7672 Red giants
We present a catalog of fundamental stellar properties for ~7500 evolved stars, including stellar radii and masses, determined from the combination of spectroscopic observations... -
LMI and LDT observation of Berkeley 50 members
We observed the Galactic open cluster Berkeley-50 in order to determine its stellar content, distance, and age. We obtained UBV photometry of 1145 stars in a 12.3x12.3' field,... -
LAMOST DR4 New mercury-manganese stars
The present work presents our efforts at identifying new mercury-manganese (HgMn/CP3) stars using spectra obtained with the Large Sky Area Multi-Object Fiber Spectroscopic... -
Physical properties of AM CVn stars
AM CVn binaries are hydrogen deficient compact binaries with an orbital period in the 5-65min range and are predicted to be strong sources of persistent gravitational wave... -
Ultra-cool dwarfs candidates in Gaia DR2
The second Gaia data release (Gaia DR2) contains high-precision positions, parallaxes, and proper motions for 1.3 billion sources. The resulting Hertzsprung-Russel diagram... -
Stellar parameters of G and K giant stars
We present results of a spectroscopic analysis of 366 G and K giant stars. For 112 stars this is the first spectroscopic analysis. The stars were selected for a radial velocity...
