Southern Cool Carbon Stars Found on Near‐Infrared Objective Prism Plates

A large set of deep, near‐IR, objective‐prism plates taken along the southern Galactic plane was searched for cool supergiants and carbon stars. Accurate coordinates and charts for 759 carbon stars in two Galactic longitude sectors within 75 of the plane, 248°<l<288° and 320°<l<341°, are given, including 289 stars not previously published. Many of the new and known stars are found in the IRAS, DENIS, and 2MASS point‐source catalogs. The 2MASS colors and the longitude distribution of cool carbon stars are discussed briefly.

New S Stars Found in a Southern Galactic Plane Survey

Based upon the presence of bands of ZrO and LaO, four new S stars have been identified. They were found among more than 700 red spectrograms of cool stars in a survey of the southern Galactic plane.

THE THIRD GALACTIC CARBON SYMBIOTIC

Of the more than 100 symbiotic stars now known in our Galaxy, only two have previously been reported to contain carbon stars as their cool components. We here present observations of a third such object, which we wish to call Weaver’s star since Weaver (1972) first identified it as a symbiotic.

Proper Motions from Schmidt Plate Scans at STScI

We describe a program of determining proper motions from digitized scans of Palomar Oschin Schmidt telescope plates at the Space Telescope Science Institute. Our method is most useful over 11 ≲ V ≲ 18 and .

A Near–IR Survey of the Southern Galactic Plane

We describe a long term project to find faint, heavily-reddened, cool supergiants and carbon stars and to classify IRAS Point Sources within 6° of the southern galactic plane. Many new supergiants and carbon stars have been found, and thousands of IRAS Point Sources have had their spectral types determined.
