... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

From the Tunguska Space Body to the Evolution of the Protoplanetary Nebula . ... A model for the structure of comet nuclei is proposed based on the results of the investigations of carbonaceous substances from the epicenter of the Tunguska cosmic body (TCB) explosion. ... Editorial note: This paper suggests several new ideas about the solar nebula and the formation and composition of comet nuclei based on investigations of the Tunguska event. ...

... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...
