3D reddening map for stars from 2MASS phot.
A three-dimensional reddening map for stars within 1100pc of the Sun are presented. Analysis of the distribution of 70 million stars from the 2MASS catalog with the most... -
New list of OB associations
A new partition into associations of OB stars within 3kpc of the Sun is derived using Battinelli's modification of the cluster analysis method. We have found 58 associations, of... -
Southern Galactic Be star candidates
We present the result of a search for southern Galactic Be star candidates within the group of miscellaneous variables of the ASAS-2 catalog of variable stars, using... -
Proper motions of faint UV-bright sources
Proper motions with values >=10 or <=10mas/yr have been extracted from the USNOB1.0 and Tycho2 catalogs for all Lanning UV-bright sources identified in the Sandage... -
LSE stars, extension of Case-Hamburg surveys.
The Case-Hamburg OB-star surveys (Luminous Stars in the Milky Way, Catalogs III/76 and III/43) have been extended to galactic latitude b=+/-30 for l=+/-60 using the Curtis... -
NIR identified X-ray sources in Galactic bulge
The presence of the apparently extended hard (2-10keV) X-ray emission along the Galactic plane has been known since the early 1980s. With a deep X-ray exposure using the Chandra... -
FUGIN. VII. Galactic plane HI clouds
We analyze molecular-gas formation in neutral atomic hydrogen (HI) clouds using the latest CO data, obtained from the FOREST (four-beam receiver system on the 45m telescope)... -
Galactic infrared bubbles
Galactic infrared (IR) bubbles, which have shell-like structures in the mid-IR wavelengths, are known to contain massive stars near their centers. Infrared bubbles in inner... -
Central Molecular Zone in H^13^CO^+^
We present results from a high-resolution wide-field imaging observation of the Central Molecular Zone (CMZ) in H^13^CO^+^ J=1-0 and SiO v=0, J=2-1 emission lines using the 45-m... -
SiO maser survey off the Galactic Plane
A group of Mira variables in the solar neighborhood shows unusual spatial motion in the Galaxy. To study this motion on a much larger scale in the Galaxy, we newly surveyed 134... -
Galactic plane VERA survey
In order to search for new VLBI sources in the galactic plane that can be used as phase reference sources in differential VLBI, we conducted 22GHz observations of radio sources... -
Sgr A East SNR multiwavelength images
Dust formation in supernova ejecta is currently the leading candidate to explain the large quantities of dust observed in the distant, early universe. However, it is unclear... -
83 newly found Galactic disk open clusters
As groups of coeval stars born from the same molecular cloud, an open cluster (OC) is an ideal laboratory for studying the structure and dynamical evolution of the Milky Way.... -
74 new open clusters found in Gaia DR2
Based on astrometric data from Gaia Data-Release 2 (DR2), we employ an un- supervised machine learning method to blindly search for open star clusters in the Milky Way within... -
Spiral structure of the Milky Way
The morphology and kinematics of the spiral structure of the Milky Way are long-standing problems in astrophysics. In this review we firstly summarize various methods with... -
K giant stars along Sagittarius streams
The Large Sky-Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 3 provided 341 691 K giant stars with stellar parameters. Based on the models of Law &... -
Candidate members of 4 stellar streams
We present candidate members of the Pal 5, GD-1, Cetus Polar and Orphan tidal stellar streams found in LAMOST DR3, SDSS DR9 and APOGEE catalogs. In LAMOST DR3, we find 20, 4 and... -
MWA Survey of Galactic HII regions
We have compiled a catalogue of HII regions detected with the Murchison Widefield Array between 72 and 231MHz. The multiple frequency bands provided by the Murchison Widefield... -
Milky Way detached double-lined EB catalog
The most accurate stellar astrophysical parameters were collected from the solutions of the light and the radial velocity curves of 257 detached double-lined eclipsing binaries... -
Distances of X-ray binaries
The X-ray luminosity functions of galaxies have become a useful tool for population studies of X-ray binaries in them. The availability of long term light-curves of X-ray...
