... 1955), and the minimal mass of the star M min =0.1 M (such a choice yields the total stellar mass in the Galaxy 10 11 M during 1.5 в 10 10 years), we find that the mean formation rate of massive stars (>10 M to produce NS) are about 1 per 30 years ...
... 1994) for the upper limit on the "cosmologically aligned" magnetic field, B0 < 10-11 G (these data were obtained from the upper bound of 5 rad m-2 on any systematic growth of the rotation measure with distance for z = 2.5), and the upper limit B0 < 10-9 G ...

... Предельная масса вычисляется по следующей простой формуле: $$ M_{Ch}=5.83\cdot\mu_e^{-2}\cdot M_{\odot}, $$ где $\mu_e$ -- молекулярная масса, приходящаяся на один электрон (эта величина связана с химическим составом звезды), а $M_{\odot}$ -- масса солнца ...
