High-resolution spectroscopic study of massive blue and red supergiants in Per OB1. I. Definition of the sample, membership, and kinematics. (2020)

Abstract:The Perseus OB1 association, including the h and chi Persei double cluster, is an interesting laboratory for the investigation of massive star evolution as it hosts one of the most populous groupings of blue and red supergiants (Sgs) in the Galaxy at a moderate distance and extinction. We discuss whether the massive O-type, and blue and red Sg stars located in the Per OB1 region are members of the same population, and examine their binary and runaway status. We gathered a total of 405 high-resolution spectra for 88 suitable candidates around 4.5 deg from the center of the association, and compiled astrometric information from Gaia DR2 for all of them. This was used to investigate membership and identify runaway stars. By obtaining ...(more)

Astronomy and Astrophysics policies
List of stars in the sample and some missing supergiants from Per OB1. Spectral classification, Gaia DR2 coordinates, photometry and astrometry, and radial velocity for the best spectrum. For stars with 5 or more spectra (excluding binaries) and for SB1 with multi-epoch data: time-span, number of spectra, average radial velocity and peak-to-peak variation. For all the stars in the sample, membership classification including whether or not each star has parallax, total proper motion, and radial velocities within 2-sigma from the mean of each distribution. Spectral variability is also indicated together with comments.
