On the “Sociality” of Several White Hypergiants

On the “Sociality” of Several White Hypergiants —Positional and kinematic parameters of hypergiants HD 168607 B8.5 Ia-0, HD 168625 B5.0 Ia-0, Schulte 12 B4.0 Ia-0, and 6 Cas A A2.5 Ia-0 belonging to OB associations do not indicate that they are ejected from their formation regions in molecular clouds, and the field hypergiant HD 183143 B7 Ia-0 located in the gap between spiral arms does not show anomalously high velocity relative to the stellar and gas neighborhood. We give two examples of the refinement of the distance to stars from the interstellar line profiles in their spectra. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Astrophysical Bulletin Springer Journals

Abstract

—Positional and kinematic parameters of hypergiants HD 168607 B8.5 Ia-0, HD 168625 B5.0 Ia-0, Schulte 12 B4.0 Ia-0, and 6 Cas A A2.5 Ia-0 belonging to OB associations do not indicate that they are ejected from their formation regions in molecular clouds, and the field hypergiant HD 183143 B7 Ia-0 located in the gap between spiral arms does not show anomalously high velocity relative to the stellar and gas neighborhood. We give two examples of the refinement of the distance to stars from the interstellar line profiles in their spectra.
