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…
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…
Non-Gaussian statistics, maxwellian derivation and stellar polytropes
E. P. Bento, J. R. P. Silva, R. Silva
In this letter we discuss the Non-gaussian statistics considering two aspects. In the first, we show that the Maxwell's first derivation of the stationary distribution function for…
An Overview of the Rotational Behavior of Metal--Poor Stars
C. Cortés, J. R. P. Silva, A. Recio-Blanco +3
The present paper describes the behavior of the rotational velocity in metal--poor stars ([Fe/H]<-0.5 dex) in different evolutionary stages, based on Vsini values from the literatu…
