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…
New Suns in the Cosmos?
D. B. de Freitas, I. C. Leão, C. E. F. Lopes +5
The present work reports on the discovery of three stars that we have identified to be rotating Sun-like stars, based on rotational modulation signatures inferred from light curves…
Overview of semi-sinusoidal stellar variability with the CoRoT satellite
J. R. De Medeiros, C. E. Ferreira Lopes, I. C. Leao +13
To date, the CoRoT space mission has produced more than 124,471 light curves. Classifying these curves in terms of unambiguous variability behavior is mandatory for obtaining an un…
A nonextensive approach to the stellar rotational evolution I. F and G type stars
D. B. de Freitas, J. R. De Medeiros
The pioneering study by Skumanich (1972) showed that the rotational velocity of G-type Main-Sequence (MS) stars decreases with stellar age according to $t^{-…
