Debris disks among Kepler solar rotational analog stars

R. Silva Sobrinho, A. D. Da Costa, B. L. Canto Martins +8

Observations of circumstellar disks provide a powerful tool for our understanding of planetary systems dynamics. Analogs to the Solar System asteroid belts, debris disks result fro…

Spectroscopic and astrometric radial velocities: Hyades as a benchmark

I. C. Leão, L. Pasquini, H. -G. Ludwig +1

We study the accuracy of spectroscopic RVs by comparing spectroscopic and astrometric RVs for stars of the Hyades open cluster. Rather accurate astrometric RVs are available for th…

On the incidence of planet candidates in open clusters and a planet confirmation

I. C. Leão, B. L. Canto Martins, S. Alves +7

Detecting exoplanets in clusters of different ages is a powerful tool for understanding a number of open questions, such as how the occurrence rate of planets depends on stellar me…

Multifractality Signatures in Quasars Time Series. I. 3C 273

A. Bewketu Belete, J. P. Bravo, B. L. Canto Martins +3

The presence of multifractality in a time series shows different correlations for different time scales as well as intermittent behaviour that cannot be captured by a single scalin…

Statistical tracing of magnetic fields: comparing and improving the techniques

Ka Ho Yuen, Junda Chen, Yue Hu +9

Magnetohydrodynamic(MHD) turbulence displays velocity anisotropies which reflect the direction of the magnetic field. This anisotropy has led to the development of a number of stat…
