Thanks For Bringing That Up, Brandon

To keep the first post uncomplicated I only discussed stable subatomic nuclei and their stellar scale dark matter analogues. When you include unstable isotopes, you get a very large array of related objects. For example, deuterium has a mass of roughly 2 Atomic Mass Units, and corresponds to your 0.145 + 0.145 = 0.290 solar mass object, which is a stellar scale deuterium analogue. The stellar scale dark matter analogue of He³ has a mass of (3)(0.145) = 0.435 solar mass. If you include these all these unstable isotopes, they pretty much fill in the the discrete mass spectrum with one subatomic nucleus or isotope for each multiple of 1 AMU. On the stellar scale this corresponds to discrete multiples of 0.145 solar mass for the dark matter objects.

Thanks again your your question, which allowed me to refine the properties of the proposed dark matter mass spectrum.
