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…
Time-dependent nonextensivity arising from the rotational evolution of solar-type stars
Jose R. P. Silva, Mackson M. F. Nepomuceno, Braulio B. Soares +1
Nonextensive formalism is a generalization of the Boltzmann-Gibbs statistics. In this formalism the entropic index q is a quantity characterizing the degree of nonextensivity, and…
On the rotation of ONC stars in the Tsallis formalism context
B. B. Soares, J. R. P. Silva
The theoretical distribution function of the projected rotational velocity is derived in the context of the Tsallis formalism. The distribution is used to estimate the average <sin…
