ИСТИНА

The dwarf irregular galaxy IC10 is the nearest starburst galaxy, which is remarkable by its number of WR stars per unit luminosity, the highest in the LG. Hα and [SII] line images of this galaxy show a giant complex of multiple shells and supeshells. The Irr galaxy IC10 is observed with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. Five spectrograms named by their position angles — PA0, PA45, PA132, PA268 and PA331 — were taken with SCORPIO focal reducer operating in the slit spectrograph mode. The data on the spectrum of gas emission in the region of ongoing star formation is reported and the relative O/H, N/O and S/O abundances are determined for about twenty HII-regions.
