Tsallis maximum entropy distribution function for stellar rotational velocities in the Pleiades

Mostrar outras versões (1)

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...
