2020-06-03 | Stochastic Core Spin-Up in Massive Stars -- Implications of 3D Simulations of Oxygen Shell Burning | It has been suggested based on analytic theory that even in non-rotating
supernova progenitors stochastic spin-up by internal gravity waves (IGWs)
during the late burning stages can impart enough angular momentum to the core
to result in neutron star birth spin periods below 100ms, and a relatively firm
upper limit of ... | 2006.02146v2 |
