Abstract:
The twelfth list of faint late M and carbon type stars detected on the
plates of the First Byurakan Spectral Survey in zone
-30°≤δ≤1° covering about 1070 sq. degrees is
presented. From 86 detected stars, 57 are newly discovered objects:
they are 3 R-type carbon stars, 2 carbon star candidates and 52 M-type
stars. Among the latter 34 (28 PSC + 6 FSC) are unclassified IRAS
sources. Equatorial coordinates, spectral classes, color indices, and
red magnitudes determined from the Palomar E-charts are presented.

History:
From electronic version of the journal
3 IRAS names corrected on 17-Jul-2002
* 05-Aug-2002 (Brian Skiff, ):
Slightly improved positions were derived from the recent astrometrical
catalogues, and the stars were matched against the GSC, IRAS PSC and
FSC, MSX, Dearborn and GCVS v4.1. Every star was searched with a 3'
radius in SIMBAD to find additional IDs. The notes include most of the
original comments; some entries have my comments added at the front
(all the external IDs given are new).
Using photometric data from the TASS MkIII survey (Cat. II/230,
2000PASP..112..397R 2000PASP..112..397R), two columns showing V and V-I to 0.1-mag.
precision were added for stars with a close match in position (∼5").
These help confirm the very-red nature of the stars.
Some of the stars are not especially red, and the spectral types
cannot be as late as indicated. This is likely to be the case when
there is no IRAS or MSX detection.
