A nonextensive insight to the stellar initial mass function

Solar and Stellar Astrophysics 2019-05-22 v1

Abstract

the present paper, we propose that the stellar initial mass distributions as known as IMF are best fitted by qq-Weibulls that emerge within nonextensive statistical mechanics. As a result, we show that the Salpeter's slope of \sim2.35 is replaced when a qq-Weibull distribution is used. Our results point out that the nonextensive entropic index qq represents a new approach for understanding the process of the star-forming and evolution of massive stars.
