In this talk, I will provide a brief overview of the key aspects of supernova matter during the final stages of stellar evolution, when the collapsing stellar core undergoes gravitational collapse and triggers a subsequent explosion. I will discuss the current knowledge on composition, relevant thermodynamic properties, and the emission of multimessengers. Additionally, I will highlight open...
The neutrinos from the core collapse SN1987A are the first extrasolar neutrinos to be ever detected and have been widely studied to infer the thermodynamical and temporal features of a supernova; however their interpretation in terms of the astrophysical properties of the explosion has been giving rise to heated debates since ever. At date, models are still under construction and simulations...
