DETECTION OF A 2ND OPTICAL-COMPONENT IN THE H-I-CLOUD OF THE YOUNG DWARF GALAXY SBS-0335-052 - NEW OBSERVATIONS WITH THE 6-M TELESCOPE

The blue compact dwarf galaxy SBS 0335-052 is one of the most metal-po or galaxies and one of the best candidates for young dwarf galaxies in the formation stage. The VLA mag of the H I distribution in this gala xy shows a rather unusual structure of neutral gas in the shape of an extended disk with a full size of about 15 galactic diameters (accordi ng to Holmberg). Two density peaks of neutral hydrogen are observed in the central region of the disk. The eastern peak coincides in positio n with SBS 0335-052 itself while the western H I peak is optically ide ntified with a very faint compact galaxy. The spectrum of this galaxy taken with the 6-m telescope exhibits the H alpha, H beta, and [O III] lambda 5007 Angstrom emission lines with a redshift close to that of SBS 0335-052. We assume that this object may be a very young dwarf gal axy in evolutionary terms.
