First results of an on-going search for Wolf-Rayet galaxies, based
on new observations obtained with the Hobby Eberly Telescope (HET) and the Marcario Low
Resolution Spectrograph
(LORES), are presented.
UM 456 and UM 594 have been found to be
normal HII galaxies. New determinations of radial velocities
have been given:
UM 456 – 
km s-1
UM 594 – 
km s-1.
Independent estimates of distances, WR/(WR+O) ratios and
oxygen to helium abundances ratios have been obtained.
Key words: galaxies: starburst / galaxies: stellar content / galaxies: individual: UM 456, UM 594 / stars: Wolf-Rayet / stars: early-type
