Abstract
Our knowledge of the spectra of stars in other galaxies is essentially limited to those which are extremely luminous. In the LMC, slit spectra of ~ 200 stars have been obtained (Feast, Thackeray and Wesselink 1960, Ardeberget al. 1972) down toUsing an objective prism technique, Brunetet al. (1975) have been able to detect 272 OB stars within the LMC. At the fainter limit this survey should include relatively normal 0 and early B dwarfs and giants. The principal aim of the present investigation was to obtain spectra of these stars for comparison with galactic stars and to apply the techniques of MK classification and measurement of Hγ equivalent widths to determine their luminosities and hence a distance modulus to the LMC.
