Recent near- and mid-infrared surveys have brought evidence that the Milky Way continues to form massive clusters. We carry out a program to determine the basic physical properties of the new massive cluster candidate [DBS2003]179. Medium-resolution K-band spectra and deep near-infrared images of [DBS2003]179 were used to derive the spectral types of eight member stars, and to estimate the distance and reddening to the cluster. Seven of ten stars with spectra show emission lines. Comparison with template spectra indicated that they are early O-type stars. The mean radial velocity of the cluster is Vrad=-77+-6 km/s. Knowing the spectral types of the members and the color excesses, we determined extinction Av~16.6 and distance modulus (m-M)0~14.5 mag (D~7.9 kpc). The presence of early O-stars and a lack of red supergiants suggests a cluster age of 2-5Myr. The total cluster mass is approximated to 0.7x10^4 Msun and it is not yet dynamically relaxed. The candidate [DBS2003]179 further increases the family of the massive young clusters in the Galaxy, although it appears less massive than the prototypical starburst clusters.
Aims. We report new results for the massive evolved and main sequence members of the young galactic cluster DBS2003 179. We determine the physical parameters and investigate the high-mass stellar content of the cluster, as well as of its close vicini
Early release science observations of the cluster NGC3603 with the WFC3 on the refurbished HST allow us to study its recent star formation history. Our analysis focuses on stars with Halpha excess emission, a robust indicator of their pre-main sequen
We present multiwavelength optical linear polarimetric observations of 69 stars toward the young open cluster Be 59. The observations reveal the presence of three dust layers located at the distances of sim300, sim500 and sim700 pc. The dust layers p
We present a comprehensive multi-wavelength study of the star-forming region NGC 1893 to explore the effects of massive stars on low-mass star formation. Using near-infrared colours, slitless spectroscopy and narrow-band $Halpha$ photometry in the cl
The study of young star cluster (YSC) systems, preferentially in starburst and merging galaxies, has seen great interest in the recent past, as it provides important input to models of star formation. However, even some basic properties (like the lum
