Hemispheric asymmetry in the sunspot cycle as a nonextensive phenomenon
Leonardo F. G. Batista, Thiago M. Santiago, Paulo C. F. da Silva Filho +2
The appearance of dark sunspots over the solar photosphere is not considered to be symmetric between the northern and southern hemispheres. Among the different conclusions obtained…
Fractal signature as a rotational modulation and stellar noise classifier based on the active Kepler stars
Paulo Cleber Farias da Silva Filho, Jose Ribamar Dantas Silveira Junior, Bricio Warney de Freitas Alves +5
In this study, we report on the analysis of 701 stars in a solar vicinity defined in three categories namely subsolar, solar, and supersolar with rotation periods between 1 and 70…
Measuring deviation from Skumanich braking index in active stars observed by Kepler mission
D. B. de Freitas, F. J. Cavalcante, T. M. Santiago
The aim of this work is to determine the deviation of the value of magnetic braking index from Skumanich canonical value for giant and main-sequence stars. In this contex…
