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…
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…
