The evolution of asymptotic giant branch stars in the Large Magellanic Cloud. II - Spectroscopy of a complete sample
Spectra of 113 asymptotic giant branch (AGB) star candidatesconstituting six magnitude-limited, area-complete samples in the outerregions of the northern LMC have been obtained. Luminosity functionsconstructed from these data are well represented by an underlyingintermediate-mass AGB population, the product of continuous starformation over the last 3-4 Gyr, supplemented in some areas by moremassive red giant and supergiant stars, with a typical age of about 10to the 8th yr. Most stars with Mbol between -5 and -5.5 show evidencefor dredge-up of s-process elements, as do a smaller proportion in therange Mbol between -4.5 and -5. Only 10 percent of the sample, however,are C stars, and these are concentrated toward the Bar of the LMC. Noevidence has been found for envelope burning in any of the stars in thesample.
