Fractal dimension and thermodynamic fluctuation properties of IDV light curves

Leung, Chun-Sing; Wei, Jian-Yan; Kovács, Zoltan +1 more

Fractals are a basic tool for phenomenologically describing natural objects having a high degree of temporal or spatial variability. From a physical point of view the fractal properties of natural systems can also be interpreted by using the standard formalism of thermodynamical fluctuations. We introduce and analyze the fractal dimension of the I…

XMM-Newton observation of the eclipsing binary Algol

Chen, Li; Aschenbach, Bernd; Lu, Fang-Jun +1 more

We present an XMM-Newton observation of the eclipsing binary Algol which contains an X-ray dark B8V primary and an X-ray bright K2IV secondary. The observation covered the optical secondary eclipse and captured an X-ray flare that was eclipsed by the B star. The XMM-Newton European Photon Imaging Camera and Reflection Grating Spectrometer spectra …
