The compression of the cloud of gas in star forming . ... These data have allowed us to create the dynamic model of the cloud of gas, around this object. ... The results on H2CO absorption lines (figure 1) have shown, that the central part of the cloud represents a clumped envelope of diameter 9 pc with radial velocity 20 km/s. The relation of radial velosity of absorption line and the whole object have allowed simple to define the direction of radial movement - itis compression. ...

... Galaxies with polar rings (PRGs) are a unique class of extragalactic objects, consisting of a ring or disk of gas, stars and dust orbiting in a plane nearly perpendicular to the disk of a central galaxy. ... At present, there are only about two dozen kinematically confirmed galaxies in this PRG class, mostly from the Whitmore et al. (1990) catalogue, based on photographic images. ... Examples of object from our catalogue SPRC (=SDSS-based Polar Ring Catalogue). ...
