SPECTROSCOPY OF H-ALPHA-EMISSION BLUE STARS IN M-33

We carried out a spectroscopic study of 59 H alpha-emission blue stars in the galaxy M 33-candidates for SS 433 and LBV objects-as part of o ur program of search for unique objects in the nearest galaxies. The s pectra and parameters of the H alpha Line and the relative intensities of the [N II] lambda 6583 and [S II] lambda 6715 lines are presented. We divided the objects into three types by the H alpha-line width: th ose with a broad, narrow, and probable broad line. The spectra of star no. 517-a candidate for LBV objects, MCA1-B-a well-known Ofpe/WN9 sta r, and v532-a candidate for WN stars, are described in more detail.
