General Catalog of Galactic Carbon Stars by C. B. Stephenson. Third Edition
The catalog is an updated and revised version of Stephenson's Catalogueof Galactic Cool Carbon Stars (2nd edition). It includes 6891 entries.For each star the following information is given: equatorial (2000.0)and galactic coordinates, blue, visual and infrared magnitudes, spectralclassification, references, designations in the most significantcatalogs and coordinate precision classes. The main catalog issupplemented by remarks containing information for which there was noplace in entries of the main part, as well as some occasional notesabout the peculiarities of specific stars.

Whither the LSR: Anticenter carbon star velocities
We report new radial measurements of 179 carbon stars toward theGalactic anticenter with accuracies of 4 km/s. We derive distances tothe carbon stars from existing K-band photometry and derive an averagegalactocentric radius of 13.9 kpc for the stars in the sample. Using thenew velocities we find that the carbon star sample is moving radiallyoutward with respect to the local standard of rest at a velocity of 6.6+/- 1.7 km/s. This is in disagreement with the nonaxisymmetric rotationcurve model proposed by Blitz & Spergel, which predicts a motion inthe opposite direction. We find no systematic difference in the peculiarmotion on either side of the anticenter and see no significant trendwith distance. The radial velocity dispersion of sample is 23 km/s anddoes not appear to vary with increasing radius.

Photoelectric photometry of carbon stars in the Vilnius system
A total of 368 observations of magnitudes and color indices of 178carbon stars in the Vilnius seven-color photometric system are given.The observations are presented in a catalog.

High-luminosity carbon stars in the galactic anticenter
K-band magnitudes of 211 carbon stars in the Galactic anticenter arepresented. The surface density, brightness range, and observed colors ofstars in the sample are discussed. It is suggested that the K-bandextinction gradient in the Galactic plane near l = 180 deg is between0.15 and 0.3/kpc. In contrast to the total density of stars, it is foundthat the density of high-luminosity carbon stars does not decrease inthe anticenter region out to at least 3 kpc from the sun. It is proposedthat this is due to the fact that lower metallicity stars spend moretime as carbon stars compared to stars of solar metallicity. Also, it isshown that the average mass-loss rates from high-luminosity carbon starsin the anticenter direction appear to be lower by a factor of 1.7 thanthose for carbon stars in the solar neighborhood.

A search for cool carbon stars. II - Anticenter region
A search for cool carbon stars has been consecutively made using the 4deg prism spectra of the Kiso 105 cm Schmidt telescope. The areasurveyed in this paper is the 200 square-deg area toward the Galacticanticenter (l=170 to 190 deg, b=-14 to +8 deg). The paper presents thecelestial position, V magnitude, and the finding chart of 125 coolcarbon stars of which 21 stars are newly descovered. The variability andthe distribution of the present sample are discussed referring to theprevious catalogs of carbon stars in this sky area.

A deep near infrared objective prism survey for carbon stars toward the galactic center and anticenter
In order to assess the problem of the asymmetric distribution of coolcarbon stars in the Milky Way for the case of a relatively faint sampleof stars, a deep, near-IR search for carbon stars has been carried outin the direction of both the galactic center and anticenter. A catalogof 283 carbon stars is presented of which 123 stars have not previouslybeen reported, and a statistical analysis of the surface and spacedistribution of the stars in the catalog indicates that the number ofcarbon stars observed toward the galactic anticenter is greater thanthat observed toward the center by a factor of 3.0. The carbon stars inthe sample appear to be concentrated at average distances from the sunof 5.5 kpc toward the galactic center, and 0.5 and 5.0 kpc toward theanticenter. Evidence is found for an increase in the population ofcarbon stars from about 2.0 kpc from the center outwards.
