Radial velocities of open stellar clusters: A new solid constraint favouring Tsallis maximum entropy theory

Carvalho, J.C.; Soares, B.B.; Canto Martins, B.L.; do … - In: Physica A: Statistical Mechanics and its Applications 384 (2007) 2, pp. 507-515

In the present study we apply a Tsallis maximum entropy distribution law to the study of the stellar residual radial velocity in a sample of 13 stellar open clusters. From a comparison between results obtained from the analysis based on Tsallis law and on the one based on the Maxwellian law we...

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

Soares, B.B.; Carvalho, J.C.; do Nascimento Jr., J.D.; … - In: Physica A: Statistical Mechanics and its Applications 364 (2006) C, pp. 413-422

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...
