New star clusters towards Galactic anticentre
We report the discovery of 31 new open clusters (OCs) identified in Gaia DR3 data through a systematic search over 220 adjacent 1{deg}*1{deg} fields towards the Galactic... -
Isochrone ages of action-angle groups in Gaia
The orbit distribution of young stars in the Galactic disk is highly structured, from well-defined clusters to streams of stars that may be widely dispersed across the sky, but... -
Velocity dispersion evolution in Sco-Cen OB
We study how the stellar velocity dispersion within the Scorpius-Centaurus OB association (Sco-Cen) has evolved over approximately 20 million years, from its formation to the... -
Taurus and Upper Sco brown dwarfs phot. and masses
Free-floating planetary mass objects -worlds that roam interstellar space untethered to a parent star-challenge conventional notions of planetary formation and migration, but... -
Nearby young moving groups IMF
The solar neighbourhood is populated by nearby (<200pc), young (<100Myr) moving groups (NYMGs) of stars, whose origins are still debated. A possible explanation is that... -
Canis Major region with Gaia-DR3
The Canis Major (CMa) star-forming region, a remote molecular cloud complex within the recently discovered Radcliffe Wave, remains underexplored in literature. We revisit the... -
Proper Motions and UBV Photometry in h+{chi} Per
Proper motions with an 80 year baseline have been determined relative to reference stars with B=13.9mag. determined for 3086 stars brighter than B=15.5mag. within an area of 50'... -
Extended Hipparcos Compilation (XHIP)
The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources.... -
Close binary system EQ Ori
The results of a UBVR photometry observations are presented for eclipsing variable EQ Ori. The binary was observed 1988 with the 1-m telescope at Maidanak Observatory (Uzbekistan). -
KV Cyg, V435 Cyg, V699 Cyg UBVR photometry
The results of a UBVR photometry observations are presented for eclipsing binaries KV Cyg, V435 Cyg and V699 Cyg. Each binary was observed 1989/91 with the 60 cm telescopes at... -
Complete sample of Galactic clump properties
The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) is an unbiased 870um submillimetre survey of the inner Galactic plane (|l|<60{deg} with |b|<1.5{deg}). It is... -
LMC Washington CMT1 photometry of star clusters
We analysed Washington CMT1 photometry of star clusters located along the minor axis of the Large Magellanic Cloud (LMC), from the LMC optical centre up to ~39{deg} outwards to... -
Kinematic data for stars in OB-associations
We use stellar proper motions from the catalog TGAS (2016, Cat. I/337) to study the kinematics of OB-associations identified by Blaha and Humphreys (1989AJ.....98.1598B). The... -
Orion Nebula Cluster members VRI photometry
Very young stars, like the Orion Nebula Cluster (ONC) members analysed in the present study, exhibit photometric variability with a wide range of amplitudes. Such a prominent... -
Cygnus OB1 association stars radial velocities
The main objective of this study is the characterization of the velocity field in the Cygnus OB1 association using the radial velocity data currently available in the... -
Scorpius-Centaurus K-Type Stars
We present results of a spectroscopic survey for new K- and M-type members of Scorpius-Centaurus (Sco-Cen), the nearest OB Association (~100-200pc). Using an X-ray, proper... -
Young and embedded clusters in Cygnus-X
We provide a new view on the Cygnus-X north complex by accessing for the first time the low mass content of young stellar populations in the region. CFHT/WIRCam camera was used... -
Nuclear star clusters photometric masses
Galactic nuclei typically host either a nuclear star cluster (NSC, prevalent in galaxies with masses <~10^10^M_{sun}) or a massive black hole (MBH, common in galaxies with... -
New Galactic star clusters and candidates
We report the discovery of 652 star clusters, stellar groups and candidates in the Milky Way with Wide-field Infrared Survey Explorer (WISE). Most of the objects are projected... -
Young moving groups in solar neighbourhood
We present a self-consistent, absolute isochronal age scale for young (<~200Myr), nearby (<~100pc) moving groups in the solar neighbourhood based on homogeneous fitting of...
