Core collapse of dense massive star clusters is unavoidable and this leads tothe formation of massive objects, with a mass up to 1000 $\msun$ and evenlarger. When these objects become stars, stellar wind mass loss determinestheir evolution and final fate, and decides upon whether they form black holes(with normal mass or with intermediate mass) or explode as a pair instabilitysupernova. In the present paper, we discuss the evolution of very massive starsand we present a convenient evolution recipe that can be implemented in agravitational N-body code to study the dynamics of dense massive clusters.Comment: 16 pages, 4 figures, 2 tables.
