Carbon stars in the Large Magellanic Cloud.
Abstract
The properties of seven carbon stars which are very likely members of the Large Magellanic Cloud are discussed. Three exhibit enhanced molecular bands of C-13, while one bears a spectroscopic resemblance to the peculiar Galactic carbon star, WZ Cas. The range in bolometric absolute magnitude for the seven stars is found to be from -5.7 to -6.6. By placing the stars in a theoretical H-R diagram, it is concluded that (1) all seven are double-shell burning stars, (2) four of the seven have just recently begun helium shell flashes and, (3) the mass range for the objects observed is from 3 to 9 solar masses.
