| Jun 7 at 10:30 | comment | added | ProfRob | @KshitijKumar I would be reluctant to get into any more details than that. | |
| Jun 7 at 10:24 | comment | added | ProfRob | @KshitijKumar "These thermal neutrinos are a coolant. They take away energy from the core, allowing it to cool by an order of magnitude in seconds"; "However, in these first few seconds after core collapse, the region just outside where these neutrinos are produced is able to absorb some of them, which drives the explosion." | |
| Jun 7 at 8:46 | comment | added | Kshitij Kumar | Also one more doubt is that the thermal energy of hot neutron core is spent in creation of neutrinos via these nuclear processes. Is my understanding correct? | |
| Jun 7 at 8:45 | comment | added | Kshitij Kumar | Ok so thanks for the answer. However I have two doubts. First the neutrinos interact with neutron core or the shockwave material? Also do they absorb energy or impart it to the shockwave, making it stronger? | |
| Jun 6 at 23:22 | comment | added | PM 2Ring | @Michael The probability of neutrino+antineutrino production is quite low, ~$10^{-19}$, but at that temperature there are a lot of electron+positron pairs being produced. Also see The photo-neutrino process in astrophysical systems | |

| Jun 6 at 16:23 | comment | added | ProfRob | @Michael yes. This conserves charge and lepton number. It is rarer than photon production because of the weak interaction involved. | |
| Jun 6 at 15:35 | comment | added | Michael | wait... electron/positron annihilation can produce neutrino/anti-neutrino pairs? | |
