Models of the Stellar Initial Mass Function,n nature. In this short contribution we review some of the current theoretical models of stellar birth. As mass is the most important parameter determining the evolution of individual stars, our focus lies on explaining the distribution of stellar masses of birth, the so-called initial mass functionuncertain 发表于 2025-3-27 08:06:18
