Principal Component Analysis studies of turbulence in optically thick gas
Caio Correia, Alex Lazarian, Blakesley Burkhart +2
In this work we investigate the Principal Component Analysis (PCA) sensitivity to the velocity power spectrum in high opacity regimes of the interstellar medium (ISM). For our anal…
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…
Stellar parameters for stars of the CoRoT exoplanet field
C. Cortés, S. C. Maciel, S. Vieira +7
Aims:To support the computation and evolutionary interpretation of periods associated with the rotational modulation, oscillations, and variability of stars located in the CoRoT fi…
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…
