Results from 6m telescope observations of globular clusters in dwarf galaxies Sharina M. We consider properties of globular clusters in dwarf galaxies observed with the multi-slit unit of the SCORPIO spectrograph at the SAO 6m telescope. ... Studying GCs in dwarf galaxies at the faintest end of the galaxy luminosity function provides valuable information for a better understanding of galaxy evolution and evolutionary connection between globular clusters and nuclei of galaxies. ...

... Many massive planets contrary to Jupiter have large eccentricities of orbits. ... Another problem is to study the conditions and boundaries of stable, regular motions of small mass planet in systems having `Jupiter' with large orbital eccentricity as well as properties of regular, stable, and irregular, chaotic motions. ... The regular eccentricity evolution described above demonstrates that stable quasi--circular orbits of small planet are unusual. ...

... 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. ...

... We consider the astrophysical evolution of the Galaxy over large time scales, from early stages (an age of ~10 8 yrs) to the end of traditional stellar evolution (~10 11 yrs). ... In the model considered, the basic stages of Galactic evolution are as follows. ... Essentially all other basic parameters of the Galaxy vary little. ... The final "stellar epoch" in the life of the Galaxy is completed ~10 13 yrs after its formation, when the evolution of the least massive stars comes to an end. ...
