Disconnection from the Termination Shock: The End of the Voyager Paradox

Recent Voyager 1 observations showed rapidly increasing galactic cosmic ray fluxes with simultaneously decreasing anomalous cosmic ray fluxes. While this has been suggested to somehow herald the imminent crossing of the heliopause, which bounds the heliosphere, we show that such observations should naturally arise from topological boundaries in the heliosphere's global magnetic topology. For a blunt termination shock, there must be a region of magnetic flux, still inside the heliopause, but beyond the last magnetic connection point to the termination shock, with poorer access for the shock accelerated anomalous cosmic rays and better access for the galactic cosmic rays entering the heliosphere (see schematic).;
