Abstract
We have analyzed the equilibrium composition of quark matter consisting of approximately equal number of up, down and strange quarks, based upon the confinement mechanism of Fowler et al. (1981) and Plummer et al. (1984) in which the quark masses are considered density dependent. Using this model, we calculate the neutrino emissivity rate and the neutrino mean free path in quark matter and compare the results with Iwamoto (1982). We find that the emissivity rate is a slowly increasing function of the density, while the values of mean free path are slightly on the higher side than those of Iwamoto.
