A couple of LBV stars in the SerOB1 A association

A couple of LBV stars in the SerOB1 A association From the concentration of stars, cold gas, and dust in the direction l = 14.◦7; b = −0.◦9, we have proved the existence of the SerOB1A association at a distance of about 2.1 kpc from the Sun and described its structure. For 29 stars belonging to the association and its vicinity, we present data on radial velocities and profiles of stellar and interstellar lines derived from original high-resolution spectra and obtained from the literature. New spectroscopic data on the unique couple HD168607 and HD168625 are given including the evidence on belonging of both stars to luminous blue variables (LBVs), proving their mutual proximity and membership in SerOB1 A, and also indicating their participation in evolution of the association. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Astrophysical Bulletin Springer Journals

Abstract

From the concentration of stars, cold gas, and dust in the direction l = 14.◦7; b = −0.◦9, we have proved the existence of the SerOB1A association at a distance of about 2.1 kpc from the Sun and described its structure. For 29 stars belonging to the association and its vicinity, we present data on radial velocities and profiles of stellar and interstellar lines derived from original high-resolution spectra and obtained from the literature. New spectroscopic data on the unique couple HD168607 and HD168625 are given including the evidence on belonging of both stars to luminous blue variables (LBVs), proving their mutual proximity and membership in SerOB1 A, and also indicating their participation in evolution of the association.
