Thermonuclear runaways in thick hydrogen-rich envelopes of neutron stars

Creators

Description

A Lagrangian, fully implicit, one-dimensional hydrodynamic computer code was used to evolve thermonuclear runaways in the accreted hydrogen rich envelopes of 1.0 Msub solar neutron stars with radii of 10 km and 20 km. Our simulations produce outbursts which last from about 750 seconds to about one week. Peak effective temperatures and luminosities were 2.6 x 107 K and 8 x 104 Lsub solar for the 10 km study and 5.3 x 106 K and 600 Lsub solar for the 20 km study. Hydrodynamic expansion on the 10 km neutron star produced a precursor lasting about 10-4 seconds
