Rotation signature of TESS B-type stars. A comprehensive analysis
L. F. Barraza, R. L. Gomes, Y. S. Messias +11
Stellar rotation is a fundamental observable that drives different aspects of stellar and planetary evolution. In this work, we present an unprecedented manifold analysis of 160 B-…
On the multiscale behaviour of stellar activity and rotation of the planet host Kepler-30
D. B. de Freitas, A. F. Lanza, F. O. da Silva Gomes +1
Kepler-30 is a unique target to study stellar activity and rotation in a young solar-like star accompanied by a compact planetary system. We use about 4 years of high-precision pho…
A search for rotation periods in 1000 TESS objects of interest
Bruno L. Canto Martins, Roseane L. Gomes, Yuri S. Messias +8
The high quality light curves from the Transiting Exoplanet Survey Satellite (TESS) represent a unique laboratory for the study of stellar rotation, a fundamental observable drivin…
New Suns in the Cosmos V: Stellar rotation and multifractality in active \textit{Kepler} stars
D. B. de Freitas, M. M. F. Nepomuceno, L. D. Alves Rios +2
In the present study, high-precision time series photometry for the active \emph{Kepler} stars is described in the language of multifractals. We explore the potential of using the…
New Suns in the Cosmos IV: the multifractal nature of stellar magnetic activity in \textit{Kepler} cool stars
D. B. de Freitas, M. M. F. Nepomuceno, M. Gomes de Souza +5
In the present study, we investigate the multifractal nature of a long-cadence time series observed by the \textit{Kepler} mission for a sample of 34 M dwarf stars and the Sun in i…
New Suns in the Cosmos III: multifractal signature analysis
D. B. de Freitas, M. M. F. Nepomuceno, P. R. V. de Moraes Junior +7
In present paper, we investigate the multifractality signatures in hourly time series extracted from CoRoT spacecraft database. Our analysis is intended to highlight the possibilit…
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…
