In Quantum FFF Theory, all stars with a planetary ring are assumed to have TWO Stellar Anchor Black Holes ( SABHs) after explosion of the star, observed as hotspots. see below:
During the creation andof stars in between these hotspots called Herbig Haro hotspots.
The southern hotspot was also suggested before UHECR, by Quantum FFF Theory based on the Herbig haro system responsible for the origin of the solar system.
