BV photometry of Bochum 7 members
We plan to identify the members of the Bochum 7 association by performing simultaneous astrometric and spectrophotometric analyses, and estimate its distance and evolutionary... -
New massive members of Cygnus OB2
The Cygnus complex is one of the most powerful star forming regions at a close distance from the Sun (~1.4kpc). Its richest OB association Cygnus OB2 is known to harbor many... -
Variability survey of brightest stars
The stellar evolution theory of massive stars remains uncalibrated with high-precision photometric observational data mainly due to small number of luminous stars monitored from... -
GSH 305+01-24 stellar content
The distribution of OB stars along with that of H{alpha}, ^12^CO, dust infrared emission, and neutral hydrogen is carried out in order to provide a more complete picture of... -
New Galactic star clusters in VVV survey
VISTA Variables in the Via Lactea (VVV) is one of the six ESO Public Surveys operating on the new 4-meter Visible and Infrared Survey Telescope for Astronomy (VISTA). VVV is... -
Properties of OB associations in IC 1613
To understand the structure and evolution of massive stars, systematic surveys of the Local Group galaxies have been undertaken, to find these objects in environments of... -
The VLT-FLAMES Survey of Massive Stars
An analysis is presented of VLT-FLAMES spectroscopy for three Galactic clusters, NGC 3293, NGC 4755 and NGC 6611. Non-LTE model atmosphere calculations have been used to... -
OB associations in the spiral galaxy NGC 300
We present results of a search for OB associations in NGC 300. Using an automatic and objective method (PLC technique) 117 objects were found. Statistical tests indicate that... -
Radio emission from stars at 250GHz
We have used the IRAM 30 m-telescope together with the Max Planck Institute for Radio Astronomy (MPIfR) bolometer to survey nearly 270 stars of different types for 250GHz... -
Survey of faint OB stars in Carina
A finding list is presented for OB stars in a 75 square degree region centered on {eta} Carinae, observed with the the 50/65/175cm Schmidt telescope of the Uppsala Southern... -
OB stars in Milky Way
(no description available) Cone search capability for table III/6/catalog (Lynga OB stars Centaurus to Norma (version: 25 Jul 2008, complete revision)) -
Faint OB stars between Car and Cen
A survey for faint OB stars between galactic longitudes 290 and 311{deg} has yielded a catalog of 284 objects. Cone search capability for table III/5A/catalog (The catalogue,... -
UBV and uvby-beta observations of Orion OB1 Association
The Catalogue of Individual UBV and uvby-beta Observations of Stars in the Region of the Orion OB 1 Association presents individual UBV observations of 106 stars in the vicinity... -
UBV Photometry of O and B Stars in Vela
Photoelectric UBV values, derived from observations made at the Boyden and ESO observatories, are presented for 358 early-type stars in the Vela section of the southern Milky... -
Masses of OB-type stars from LAMOST DR5
The measurements of masses and luminosities of massive stars play an important role in understanding the formation and evolution of their host galaxies. In this work, we present...
