报告摘要：Core-collapse supernova marks the death of massive stars with mass ≳8M⊙, and leaves behind a compact remnant, i.e., neutron star or black hole. During such a violent collapse, its central density can increase to ∼(1∼10)×ρsat (ρsat∼1014 g/cm3) and the temperature may also reaches several tens MeV. The thermodynamic conditions realized throughout this evolution reside in the QCD phase diagram between those of heavy-ion collisions and cold neutron stars. Meanwhile, most (∼99%) of the released gravitational potential energy (∼1053 erg) of the progenitor star is ultimately liberated through neutrino emission within a ∼10s burst. This provides us a unique playground to study the properties of hot dense matter and elusive neutrinos. In this talk, I will show our results on studying some interesting topics in particle and nuclear physics in relation to core-collapse supernovae, such as hadron-quark phase transition and nonstandard neutrino physics.
Dr. Xu-Run Huang graduated and obtained his master degree from Harbin Institute of Technology in 2018 and finished his PhD program, under the supervision of Prof. Lie-Wen Chen, from Shanghai Jiao Tong University in 2022. He subsequently conducted postdoctoral research at the Chinese University of Hong Kong. His research focuses on studying neutrino and nuclear physics related to core-collapse supernova.
