First Byurakan spectral sky survey. Stars of late spectral types. IX. -15 ≤ δ ≤ -11° belt.
Abstract
A ninth list of late-type M and C stars found on plates of the First Byurakan Spectral Sky Survey in the -15 ≤ δ ≤-11° belt is given. Of the 123 selected objects, 83 were found for the first time (82 M stars and one carbon star of an early R0–R1 subtype). Of the 83 objects found for the first time, 15 are unidentified IRAS sources. It is established that 15 associated objects belong to spectral type M. Some new data are also given for the x-ray source 2E0019.2 — 1247. The equatorial coordinates, spectral types, and stellar magnitudes in the red band are given for the selected objects.
