Such hotspots which we observe now, in our neighborhood are second- or third generation new physics micro black holes, according to Quantum FFF Theory.
Nature seems to have a self seeding mechanism of dual Herbig Haro hotspot creation.
Small black holes are created around massive stars by interference of magnetic storms, also resulting in cometary nuclei.
Comet nuclei crashing into stars seem to create and populate "starspots"in dual- or triple hotspot order.

The origin: Dual pressure gravity on baryons (graviton and Axion vacuum pressure) and single pressure gravity on black holes (Axion/Higgs vacuum pressure)
