    • Abstract

       

      Based on Shannon entropy transfer estimation technique and Stanford’s solar global magnetic field harmonic coefficients, several new facts about solar magnetic modes have been found. The entropy transferring between most of the modes has been subjected to a steady modulation with a period near 72 solar rotations (5.38 years). As a rule, the amplitudes of entropy transferring modulation were less or equal to 0.1 bit/solar rotation. These modulations had no relations with intensity or configuration of the solar magnetic fields. Besides,Shannon entropy exchanges have been found between some modes—the sign of dependencies of them. Such modes had sector nature. The influence of a magnetic mode on another is strongest with the delay time between the two modes being twenty to forty solar rotations. Special properties have been revealed for zonal modes also.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
