Starburst wind from the nucleus of NGC 7714

Kinematic evidence for a starburst-driven wind from the nucleus of the galaxy NGC 7714 is reported. The velocity field of the circumnuclear ionized gas is analyzed, and the observed properties of the circumnuclear gas are discussed. The wind shows a twofold pattern: (1) bipolar winds nearly perpendicular to the disk plane and (2) expanding lobes within the disk plane. 57 references.

A photometric and spectroscopic study of the eclipsing symbiotic binary AX Persei

We analysed photometric and spectroscopic optical observations of the eclipsing symbiotic binary AX Persei. For the first time, we present and discuss its historical, 1887-1999, photographic/ B -band and visual light curve (LC). The red giant in AX Per losses mass via the wind at a rate of
