Dynamo beyond the Heliopause: Verification from the Available Data of Voyager 2

Abstract

A possible dynamo mechanism beyond the heliopause is proposed to explain the increase in the magnetic field without change in its direction, which was observed by the Voyager 1 and Voyager 2 space probes upon crossing the heliospheric boundary. The necessary conditions for the dynamo realization are listed and it is shown that they are fulfilled beyond the heliopause. The fulfillment of the necessary conditions does not guarantee the realization of the dynamo mechanism, but it creates the prerequisites for it. The paper is based on the report made at the conference “Ideas of S.B. Pikelner and S.A. Kaplan and Modern Astrophysics” (Sternberg Astronomical Institute, Moscow State University, February 8–12, 2021).
