Rotation period distribution of CoRoT and Kepler Sun-like stars
I. C. Leão, L. Pasquini, C. E. Ferreira Lopes +9
We study the distribution of the photometric rotation period (Prot), which is a direct measurement of the surface rotation at active latitudes, for three subsamples of Sun-like sta…
Stellar Cycles from Photometric Data: CoRoT Stars
C. E. Ferreira Lopes, I. C. Leão, D. B. de Freitas +3
Until a few years ago, the amplitude variation in the photometric data had been limitedly explored mainly because of time resolution and photometric sensitivity limitations. This i…
The variability behavior of CoRoT M-giant Stars
C. E. Ferreira Lopes, V. Neves, I. C. Leão +8
For 6 years the Convection, Rotation, and Planetary Transits (CoRoT) space mission has acquired photometric data from more than one hundred thousand point sources towards and direc…
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…
The rotational behavior of Kepler Stars with Planets
F. Paz-Chinchón, I. C. Leão, J. P. Bravo +6
We analyzed the host stars of the present sample of confirmed planets detected by Kepler and Kepler Objects of Interest (KOI) to compute new photometric rotation periods and to stu…
