All star formation is postulated and explained by the new Q-FFF- Vuyk string model as the result of 2x Herbig Haro repelling black holes of equal size (15% differences) at the start of star formation in between these two ( mostly) small black holes.
In the early universe it is to be expected, that larger black holes even giant BHs (spitted out of the Big Bang) would do the same star forming job, but now not any more.
The origin of attraction, but also repulsion at close range of both black holes, is explained by the Penrose Vuyk "Trapped spacetime horizon", which is a combination of "Penrose trapped space horizon" with the Vuyk Fermion Repulsion horizon of all black holes and the (<15%)
MOST LIGO Black Hole mergers of the past observations is smaller than 15%.
THIS was leading to the postulate that Stars are born out of the combination of two 155 equal sized black holes forming a new Herbig Haro system with two Bow shock ( black holes) receding from each other, called SABHs ( Stellar Anchor Black Holes.)
The BHs seem to be the origin of a Plasma production ( Q-FFF Fermion horizon fermion production and repelling out of the vacuum), local vacuum polarization ( by the deformation of the Axion Tetrahedral space frame variable Planck fluxtubes) and Birkeland electric current circuits between the two negative charged SABHs and the forming positive charged star in the middle.

Over densities of dual Herbig Haro Hotspot bowshock black holes forming stars in between after a start as X-SHAPED RADIO SOURCE. : Carina: Dual Herbig Haro Bowshocks (former crashed comet star spots, became small Black Holes, after S-Nova Nebula explosion, propelled by plasma tails) made visible in the IR Hubble image as an overdensity of dual hotspots ( Q-FFF model.)
Even the whirlpool galaxy shows the same structure os two arms as the former paths of the two equal sized black holes,
However, these arms seem to show splitting smaller black holes o form stars by smaller Herbig Haro systems.
