The two Herbig Haro black holes keep the balance between inflow and outflow of stars by their own influence on the local vacuum gravitational dark energy.
The in-flowing Hydrogen of the star, is assumed to be produced by both Fermion repelling Herbig Haro black holes ( SABHs: Stellar Anchor Black Holes, see: E-FFF Theory) starting a so called Birkeland Alfven circuits.
