... A correlation between metal abundance and orbital elements (the eccentricity and angular momentum) has been found for three semples of disk stars of our Galaxy with abundance derived from detailed analysis. The correlation indicates that metal abundance in the Galaxy kept increasing after the birth of old disk stars and that the Galaxy kept collapsing during the formation of its disk subsystems. ...

... The observed isotropy on the sky and non-uniform spatial distribution of gamma-ray bursts   (GRB) revealed by the BATSE   device onboard the Compton Gamma-Ray Observatory (e.g. Meegan et al. , 1992)[ 138 ] lend support to the idea of a cosmological origin of GRB (Prilutski and Usov, 1975;[ 165 ] Usov and Chibisov, 1975)[ 199 ] for which the best candidates could be merging binary NS+NS   or NS+BH   at high redshifts (z 1 -2), (Blinnikov et al. ...
