The fully developed remnant of a neutrino-driven supernova: Evolution of ejecta structure and asymmetries in SNR Cassiopeia A

S. Orlando, A. Wongwathanarat, H. -T. Janka +5

Abridged. We aim at exploring to which extent the remnant keeps memory of the asymmetries that develop stochastically in the neutrino-heating layer due to hydrodynamic instabilitie…

3D MHD modeling of the expanding remnant of SN 1987A. Role of magnetic field and non-thermal radio emission

S. Orlando, M. Miceli, O. Petruk +8

Aims. We investigate the role played by a pre-supernova (SN) ambient magnetic field on the dynamics of the expanding remnant of SN 1987A and the origin and evolution of the radio e…
