Massive Stellar Content of the Galactic Supershell GSH 305+01-24
N. Kaltcheva, V. Golev, K. Moran
The distribution of OB stars along with that of H, CO, dust infrared emission, and neutral hydrogen is carried out in order to provide a more complete picture of interact…
Stellar content of the young supershell GSH 305+01-24
N. Kaltcheva, V. Golev
We combine several surveys at different wavelengths with intermediate-band photometry to examine the correlation between the location of the OB-stars in the Centaurus star…
The field of Loden 112
Nadia Kaltcheva, Valeri Golev
Based on the available uvbybeta photometry of OB stars in the longitude range 281 - 285 deg in the Galactic disk, we identify a feature of young stars at 1630+/-82 pc, that is prob…
Improved distances to several Galactic OB associations
Nadia Kaltcheva, Valeri Golev
Based on uvbybeta photometry we study the structure of several Galactic star-forming fields. Lac OB1 is a compact association at 520+/-20 pc spatially correlated with a region of i…
Revised distances to several Bok globules
Jens Knude, Nadia Kaltcheva
Distances to Bok globules and small dark nebulae are important for a variety of reasons. We provide new distance estimates to several small clouds, some of them known to harbor YSO…
The Structure and the Distance of Collinder 121 from Hipparcos and Photometry: Resolving the Discrepancy
N. Kaltcheva, V. Makarov
We present further arguments that the Hipparcos parallaxes for some of the clusters and associations represented in the Hipparcos catalog should be used with caution in the study o…
