Numerical results of collapse simulation (one-zone code) Anthea F. Fantina - Seminar @ LUTH, Meudon, 2nd April 2009 “Standard” parameters:
Physical model – 1D Newtonian • 1D code Newtonian ( Blottiau P., PhD thesis (1989) ) - sphere divided in 40 zone for core, total 100 zone - Lagrangian treatment, implicit scheme • Matter made up by: - nuclei (A, Z), neutrons and free protons (classical e non relativistic) - electrons and neutrinos (degenerate and ultra relativistic) ⇒ EoS BBAL ( Bethe H.A. et al., Nucl. Phys. A324, 487 (1979) ) Fuller ( Fuller G.M., Astrophys. J. 252, 741 (1982) ) + increasing of Γ to simulate stiffness of EoS • Hydro equation coupled to equation for electron fraction evolution and capture • Neutrino transport: multigroup, inclusion of different N p * N h ( Bruenn S., Astrophys. J. Suppl. 58, 771 (1985) ) • Trapping comes out “automatically” Anthea F. Fantina - Seminar @ LUTH, Meudon, 2nd April 2009
