... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

. The temperature of degenerating is the temperature below which there appear the quantum effects connected with the indenty of the particles. For bose-gas this temperature Td is equal to the one below which the condensation of Bose-Einstein occurs. Td = Ef/ k , where Ef - maximum energy of particles at T = 0 (fermy-energy), k - constant of Boltzman ( k = 1,3807*10^-23 Dg/K). Back .
