Astrophysics Aims and scope

Abstract

A preliminary analysis is given of 2D spectroscopic data on the galaxy SBS 1533+574(AB) obtained using the multipupil spectrographs on the 2.6-m telescope at the BAO (VAGR) and the 6-m telescope at the SAO (MPFS). The two components of the galaxy are star formation regions in different stages. The component SBS 1533+574B is known to be a BCDG. The plots of the intensity distribution of the radiation in the recombination lines of hydrogen and the forbidden lines of gases with a low degree of ionization obtained here make it possible to compare the basic characteristics of the HII-zones and the surrounding shell. The velocity distribution over the field of the galaxy is indicative of a common rotation of the system and of an intrinsic rotation of the components which is more distinct for component B.
