A nonextensive insight to the stellar initial mass function

the present paper, we propose that the stellar initial mass distributions as known as IMF are best fitted by \(q\)-Weibulls that emerge within nonextensive statistical mechanics. As a result, we show that the Salpeter's slope of \(\sim\)2.35 is replaced when a \(q\)-Weibull distribution is used...

Summary:the present paper, we propose that the stellar initial mass distributions as known as IMF are best fitted by \(q\)-Weibulls that emerge within nonextensive statistical mechanics. As a result, we show that the Salpeter's slope of \(\sim\)2.35 is replaced when a \(q\)-Weibull distribution is used. Our results point out that the nonextensive entropic index \(q\) represents a new approach for understanding the process of the star-forming and evolution of massive stars.
