Abstract:
Multiobject spectroscopy for 118 blue stars with an Hα excess in
the galaxy M 33 from the lists of SS 433 and LBV candidates and other
rare types of massive stars is presented. The Hα parameters and
the relative intensities of the [NII]6584Å and [SII]6716Å lines
are given. We identified stars with a broad Hα emission line,
which is probably emitted in the stellar wind.

Several stars have designations from Ivanov' catalogue
(1993, Cat. J/ApJS/89/85):
I: blue stars (IFM-B NNNNa in Simbad),
IR: red stars (IFM-R NNN in Simbad)
No. 2 to 526 are identified as FSZ NNN in Simbad
No. L25 to L167 are identified as LMA M 33 NNN in Simbad
No. I141 to I1430 are identified as IFM-B NNNN in Simbad

Note (3): Vmag are taken from Ivanov et al. (1993, Cat. J/ApJS/89/85)
Note (4): Hα FWHM types:
1: with a broad line (FWHM > 150 km/s)
2: with a narrow line (FWHM < 150 km/s)
3: with a broad line, if the spectrum quality was not high enough to
reliable measure the profile parameter,
or if a Gauss analysis revealed a narrow line, but its profile
shows a characteristic feature (broad or asymetric wings, or
P-Cyg-type wings)
