Supermassive neutrino stars and galactic nuclei

Viollier R.D. ; Trautmann D. ; Tupper G.B. (1993)


The characteristics of supermassive 'stars' consisting of self-gravitating degenerate neutrino (or neutralino) matter are studied with particular emphasis on fermion masses around 17 keV/c2. Such compact dark objects could be as massive as 109.5 to 106.5 solar masses, with radii of about one to ten light days; they might thus mimic phenomena that are expected around the supermassive black holes recently purported at the centres of some galaxies and quasi-stellar objects.
