J/other/Ap/44.335   M stars in Cepheus region                (Kazarian+, 2001)

near-infrared range.

Description:
    The results of a spectral classification of 257 M stars observed in
    the Cepheus region are given. Their equatorial coordinates,
    photographic stellar magnitudes, and spectral subtypes were
    determined. These stars are giants and supergiants, in all
    probability. None of them appear in a catalog of variable stars. It is
    assumed that variability might be detected in many of them upon
    further study. Fifty-two of the stars have been identified with
    infrared sources.

    In addition to the originally published data, magnitudes, positions,
    cross-identifications and notes have been added in May 2002.

History:
  * From electronic version of the journal
  * 17-May-2002: Some corrections in the IRAS numbers
  * 23-May-2002: A new version has been prepared by Brian Skiff
    ():
    the list was matched against the IRAS, MSX, and Dearborn red-star
    catalogues, and the coordinates were added, mostly from GSC-ACT (Cat.
    I/255) or USNO-A2.0 (Cat. I/252); two stars (#46 and #174) could not
    be recovered. Notes were added in the course of this work.
