Consider astrophysical jets. One thing that astrophysical systems like black holes, quasars, young and proto-stars, pulsars, Seyfert (and other classes of) galaxies, Haro-Herbig stars, and many other astrophysical objects regularly do is emit high-energy jets of matter and radiation energy.
These many forms of jet phenomena are not well understood. Discrete Scale Relativity interprets this very general phenomenon as the systems ejecting additional mass that exceeds the allowable mass for that system.
A good way to test the predicted quantum-like mass distribution of stellar-mass objects is through the mass spectrum of the dark matter, assuming it is composed of stellar-mass black holes. These dark matter objects are predicted to have quantized masses in multiples of 0.145 solar mass. This should eventually be vindicated if DSR’s dark matter prediction is correct.
One of the pages at http://www3.amherst.edu/~rloldershaw discusses “Stellar Scale Discreteness”, and this idea is also discussed at other places at that website.
