Tsallis maximum entropy distribution function for stellar rotational velocities in the Pleiades
In the present study we use a Tsallis maximum entropy distribution law to fit the observed distribution of projected rotational velocity measurements of stars in the Pleiades open cluster. This new distribution function which generalizes the Maxwell–Boltzmann one is derived from the non-extensivity...

Resumo: | In the present study we use a Tsallis maximum entropy distribution law to fit the observed distribution of projected rotational velocity measurements of stars in the Pleiades open cluster. This new distribution function which generalizes the Maxwell–Boltzmann one is derived from the non-extensivity generalization of Boltzmann–Gibbs entropy. We present a comparison between results from the generalized distribution and the Maxwellian law and show that the generalized distribution fits more closely the data |
