We show that although the time of formation of horizon, evolution of the mass and proper radius are independent of the chosen initially static conﬁgurations, there is a signiﬁcant diﬀerence in the temperature proﬁles of the radiating bodies as the collapse proceeds.14 penHydrostatic equilibriumShear-free conditionDissipationThe inﬂuence of initial conditions during dissipative collapseArticle10.1142/S0218271816500929
