The present paper shows that the analysis of full flow X-ray activity signals recorded by the ASM (All-Sky Monitor) survey camera of RXTE (Rossi X-ray Timing Explorer) orbital observatory for binary systems allows for not only establishment of some mechanisms of matter accretion in binary star systems but classification depending on manifestation of statistical memory effects as well. As an example, using frequency dependencies of autocorrelators and their derivatives calculated on the basis of Memory Function For...

The aim of this article is to study astronomical refraction anomalies. Back in 1925 Grachev and Banahevich found systematic errors in meridian observations depending on zenithal distance. Grachev suggested that these refraction anomalies arise from the inclination of the Earth's surface to the South. The airstratas of the same density were considered as parallel to the Earth's surface. But the analysis of latitude observations from the Bamberg and ZTL-180 telescopes showed there were significant systematic errors ...
