On the possibility of joint generation of cosmic rays and gamma-bursts in plasma pinches

Summary form only given, as follows. The authors suppose that Galactic cosmic rays (GCRs) are generated (as a proton component) in plasma cosmic pinches at the same time as gamma-bursts (GBs) (as an electron component producing the bremsstrahlung). As is known, the power W/sub p/=2/spl times/10/sup 40/ erg/s is needed for sustaining GCRs. In the case of a "pinch mechanism" the power of an electron fraction would be 1/2000-times smaller, W/sub e/=10/sup 37/ erg/s from all the GB-sources, the number of which in the Galaxy can be estimated in the following way. Approximately one GB, 5 s long, with energy fluxes in the range from 10/sup -6/ to 10/sup -3/ erg cm/sup -2/ s/sup -1/, is registered per 24 hours. However, the distance is unknown. The authors assume that weak GBs are the most remote, at a distance R/sub max/, and assume that one GB releases energy E/sub 1/[erg]=6/spl times/10/sup -5/(R/sub max/[cm])/sup 2/ per 24 hours within a sphere with the volume V/sub 1/=(4/3)/spl pi/R/sub max//sup 3/. In the vicinity of the Sun, the star density is equal to /spl rho/=0.05 M/sub /spl odot// pc/sup -3/, thus the number of stars in this sphere is N=/spl rho/V/sub 1//M/sub /spl odot//=7.4/spl times/10/sup -57/(R/sub max/[cm])/sup 3/. Therefore the GB power per star is W/sub */=10/sup 47//(R/sub max/[cm]) erg/s, and, since the Galaxy includes 10/sup 11/ stars, their total GB power is W/sub /spl gamma//=10/sup 58//(R/sub max/[cm]) erg/s. If one assumes that W/sub /spl gamma//=W/sub e/, one finds R/sub max/=330 pc, and R/sub min/=10 pc. The number of stars within a sphere having R/sub max/ is equal to 10/sup 7/ and provides the observed GB source distribution isotropy in all directions. The produced estimates allow one to assume that the GCRs and GBs emerge simultaneously in the "cosmic lightnings" which occur, from time to time, in the magnetized plasma clouds produced from "stellar winds" at distances R/sub min//spl sim/10 pc around each star.
