On the equipartition theorem and black holes nongaussian entropies
Everton M. C. Abreu, Jorge Ananias Neto, Edésio M. Barboza +2
In this Letter we have shown that, from the standard thermodynamic functions, the mathematical form of an equipartition theorem may be related to the algebraic expression of a part…
Black holes quasinormal modes, Loop Quantum Gravity Immirzi parameter and nonextensive statistics
Everton M. C. Abreu, Jorge Ananias Neto, Edesio M. Barboza +1
It is argued that, using the black hole area entropy law together with the Boltzmann-Gibbs statistical mechanics and the quasinormal modes of the black holes, it is possible to det…
Non-Gaussian thermostatistical considerations upon the Saha equation
Bráulio B. Soares, Edésio M. Barboza, Everton M. C. Abreu +1
The Saha equation provides the relation between two consecutive ionization state populations, like the Maxwell-Boltzmann velocity distribution of the atoms in a gas ensemble. Saha…
A nonextensive view of the stellar braking indices
D. B. de Freitas, F. J. Cavalcante, B. B. Soares +1
The present work is based on a description for the angular mometum loss rate due to magnetic braking for main-sequence stars on the relationship between stellar rotation and age. I…
Chandrasekhar's relation and the stellar rotation in the Kepler field
J. R. P. Silva, B. B. Soares, D. B. de Freitas
According to the statistical law of large numbers, the expected mean of identically distributed random variables of a sample tends toward the actual mean as the sample increases. U…
Strong evidences for a nonextensive behavior of the rotation period in Open Clusters
D. B. de Freitas, M. M. F. Nepomuceno, B. B. Soares +1
Time-dependent nonextensivity in a stellar astrophysical scenario combines nonextensive entropic indices derived from the modified Kawaler's parametrization, and , obtai…
