NONADIABATIC GRAVITATIONAL COLLAPSE IN HIGHER-DIMENSIONAL SPACE-TIME AND ITS JUNCTIONS CONDITIONS

Junction conditions are studied at the boundary of a higher dimensiona l spherical distribution containing an outgoing heat flow and radiatio n flux. Our analysis extends to higher dimension, an important observa tion of Santos that for a collapsing fluid with radial heat flow the i sotropic pressure on the surface of discontinuity does not vanish. Som e physically relevant parameters like luminosity, mass function for th e bounded distribution and also the time required for horizon formatio n are also calculated and it is observed that the dimensionality of sp ace-time does not qualitatively alter the analogous results of the 'st andard' space time.
