Neutrino burst and gravitational wave from supernova explosions
Katsuhiko Sato,Kei Kotake,Keitaro Takahashi,Shin'ichiro Ando 한국물리학회 2004 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.45 No.1
The time prole and energy spectrum of a neutrino burst from supernovae is greatly modied by the eect of neutrino oscillations. We review how these conversions happen in a supernova mantle and how the burst could be detected by SK (Super-Kamiokande) and SNO (Sudbury Neutrino Observatory). We show that implications for neutrino parameters (mass hierarchy and the mixing angle between mass eigenstate 1; 3), can be obtained if a supernova appears at the Galactic Center. We also discuss the eects of neutrino oscillation on the supernova relic neutrino observations. In the end, we discuss the gravitational radiation from the rotating stellar cores, which will give us the information of the angular momentum distribution for evolved massive stars.
