Optimized cutting off transit algorithm to study stellar rotation from PLATO mission light curves

Leandro de Almeida, Francys Anthony, Ana Carolina Mattiuci +4

Measuring the stellar rotation of one of the components in eclipsing binaries (EBs) or planetary systems is a challenging task. The difficulty is mainly due to the complexity of an…

Spectroscopic and asteroseismic analysis of the secondary clump red giant HD 226808

Bruno Lustosa De Moura, Paul G. Beck, Leandro de Almeida +5

In order to clarify the properties of the secondary clump star HD 226808 (KIC 5307747), we combined four years of data from Kepler space photometry with high-resolution spectroscop…

Is the primary CoRoT target HD43587 under a Maunder minimum phase?

Rafael Ramon Ferreira, Rafaella Barbosa, Matthieu Castro +4

One of the most enigmatic phenomena related to solar activity is the so-called Maunder minimum phase. It consists of the lowest sunspot's counting ever registered for the Sun, and…

Orbital period variation of KIC 10544976: Applegate mechanism versus light travel time effect

Leonardo A. Almeida, Leandro de Almeida, Augusto Damineli +6

In recent years, several close post-common-envelope eclipsing binaries have been found to show cyclic eclipse timing variations (ETVs). This effect is usually interpreted either as…

Microlensing path parametrization for Earth-like Exoplanet detection around solar mass stars

L. de Almeida, J. -D. do Nascimento

We propose a new parametrization of the impact parameter u0 and impact angle α for microlensing systems composed by an Earth-like Exoplanet around a Solar mass Star at 1 AU. We pre…
