Neutrino Flavor Transformation in Collapsing Supermassive Objects

Kyle S. Kehrer, George M. Fuller, Ian Padilla-Gay +1

The collapse of supermassive stars (SMSs, $M ≳ 1 0^{4} M_{⊙}$ ) to black holes is accompanied by a prodigious flux of neutrinos of all flavors. These are produced thermally via…

Early Formation of Supermassive Black Holes via Dark Star Gravitational Instability

Katherine Freese, George M. Fuller, Sohan Ghodla +4

We show that dark stars, which are dark-matter-powered stars in the early universe, can grow by accretion to masses in the range $\mathscr{O}\left ({10}^4\right )-\mathscr{O}\left…

Dark Matter and General Relativistic Instability in Supermassive Stars

Kyle S. Kehrer, George M. Fuller

We calculate the extent to which collisionless dark matter impacts the stability of supermassive stars $(M ≳ 1 0^{4} M_{⊙})$ . We find that, depending on the star's mass, a dark…
