Dust formation in the Cassiopeia A supernova
High angular resolution (6") spectro-imaging observations of Cassiopeia A, the youngest supernova remnant of our galaxy, were performed with ISOCAM, the mid-infrared camera on board of the Infrared Space Observatory (ISO). The remnant was fully mapped with the LW8 filter (10.7-12 m), which probes mainly dust thermal emission. Emission is seen both from the blast wave region and the inner region...
متن کاملDust Formation and Survival in Supernova Ejecta
The presence of dust at high redshift requires efficient condensation of grains in SN ejecta, in accordance with current theoretical models. Yet, observations of the few well studied SNe and SN remnants imply condensation efficiencies which are about two orders of magnitude smaller. Motivated by this tension, we have (i) revisited the model of Todini & Ferrara (2001) for dust formation in the e...
متن کاملSupernova Explosions and Neutron Star Formation
The current picture of the collapse and explosion of massive stars and the formation of neutron stars is reviewed. According to the favored scenario, however by no means proven and undisputed, neutrinos deposit the energy of the explosion in the stellar medium which surrounds the nascent neutron star. Observations, in particular of Supernova 1987A, suggest that mixing processes play an importan...
متن کاملFormation of the three-ring structure around supernova 1987A.
From a magnetohydrodynamic simulation, we reproduce a three-ring structure in the circumstellar space of the supernova (SN) 1987A observed by the Hubble Space Telescope. When a star develops from a red supergiant (RSG) to a blue supergiant (BSG) just before the SN explosion, a wind-wind interaction occurs between the slow stellar wind from the RSG and the subsequent fast stellar wind from the B...
متن کاملThe diffuse supernova neutrino flux, star formation rate and SN1987A
I calculate the diffuse flux of electron antineutrinos from all supernovae by imposing compatibility with the SN1987A neutrino data and with the existing constraints on the cosmological rate of core collapse supernovae. For the latter I use observational results on the cosmological star formation rate, taking into account the error on the ratio of the supernova rate and star formation rate. The...
