Accretion Onto Endoparasitic Black Holes At The Center Of Neutron Stars, Chloe B. Richards
Accretion Onto Endoparasitic Black Holes At The Center Of Neutron Stars, Chloe B. Richards
Honors Projects
We revisit the system consisting of a neutron star that harbors a small, possibly primordial, black hole at its center, focusing on a nonspinning black hole embedded in a nonrotating neutron star. Extending earlier treatments, we provide an analytical treatment describing the rate of secular accretion of the neutron star matter onto the black hole, adopting the relativistic Bondi accretion formalism for stiff equations of state that we presented elsewhere. We use these accretion rates to sketch the evolution of the system analytically until the neutron star is completely consumed. We also perform numerical simulations in full general relativity for …
