The Abundances of Charged Particles in Protostellar CoresWe investigate the abundances of charged particles in very dense (10(exp 5) cm(exp -3) approx. less than n(sub H2) approx less than 10(exp 14) cm(exp -3) molecular cloud (protostellar) cores. We focus on the dust grains, which are the dominant charge carriers for high densities. Previous studies have investigated the abundances of charged grains in the case that the grain radii follow an MRN distribution. We account for the transfer of charge between grains of different size, an effect that was ignored in previous calculations, but which is significant in determining the total abundance of charged grains. The consequences for star formation are considered.
