r-Process nucleosynthesis from hyperaccreting neutron stars in common envelopes
Peter Anninos, Matthew Portman, Scott Carmichael +2
We investigate nuclear reactions and feedback in hyperaccreting neutron star environments, considering accretion rates in the range 0.3 - yr, typical…

X-ray Spectra from General Relativistic RMHD Simulations of Thin Disks
Nathaniel Roth, Peter Anninos, P. Chris Fragile +1
We compare X-ray emission from several general relativistic, multi-frequency, radiation magnetohydrodynamic simulations of thin black hole accretion disks with different accretion…

Stability and convergence of nuclear detonations in white dwarf collisions
Peter Anninos, David Cruz-Lopez, Brighten Jiang +1
We investigate the numerical stability of thermonuclear detonations in 1D accelerated reactive shocks and 2D binary collisions of equal mass, magnetized and unmagnetized white dwar…
