Research of signs of star formation in three S0 galaxies – members of isolated pairs
We obtained and analyzed long-slit spectra of three lenticular galaxies with optical rings: PGC 48114, ESO 234-011, and ESO 444-076. Ionized gas was detected in all of them. In PGC 48114, the excitation mechanism of the ionized gas differs along the ring, despite the consistent kinematics of the ionized gas and stars...
