12. How to make a supernova associated with a Gamma-Ray Burst in the collapsar model ?

Mr Tomoyasu Hayakawa (Kyoto University)

Short Talk

Gamma Ray Bursts (GRBs) are among the most energetic events in the universe. GRBs are divided by the duration time into long GRBs and short GRBs. A popular model of the central engine of long GRBs involves a hyper accreting black hole (BH), created by a core collapse of a massive star (the collapsar model) [1]. Indeed, supernovae (SNe) have been observed to be associated with some GRBs since...

16. Pairing dynamics in Richardson model

Mr Fang Ni (Univ. of Tsukuba)

Short Talk

Nuclei show a variety of collective phenomena. Especially, excited $0^+$ states in even-even nuclei show puzzling properties. Recent experiments reveal anomalous properties of the low-lying $0^+$ states. We presume that the pairing dynamics plays a significant role in these low-lying excited $0^+$ states. For instance, the $0_2^+$ states in $^{152}$Sm and $^{154}$Gd, which were interpreted as...

17. β-decay studies of r-process nuclei using the Advanced Implantation Detector Array (AIDA)

Mr Chris Griffin (University of Edinburgh)

15/06/2016, 14:30

Short Talk

The origin of the heavy elements is one of the most fundamental open questions in modern astrophysics, with a notable difficulty being the lack of a complete description of the rapid neutron-capture process (r-process) [1]. Two key quantities used in r-process calculations are β-decay half-lives and β-delayed neutron emission probabilities. The half-lives determine the timescale for the flow...

22. Evolution of the magnetar-powered supernovae

Ms Miyu Masuyama (University of Tokyo, Research center for the early universe)

15/06/2016, 14:40

Short Talk

Magnetars are neutron stars with strong magnetic fields(B~10^14-10^15G). The mechanism to make such a strong magnetic field and what kind of supernova generates a magnetar have not been well understood. Recent observations of supernova remnants associated with magnetars indicate that magnetar progenitors are massive stars and the typical explosion energy is 10^51 erg (e.g. Kumar et al., 2014,...

25. Searching for the origin of galactic Al-26 with an experiment using isomeric Al-26 beam

Mr Hideki Shimizu (CNS, University of Tokyo)

15/06/2016, 14:50

Short Talk

We will present an experimental plan to measure proton resonant elastic scattering with a thick target in inverse kinematics with a novel beam of isomeric Al-26 to be produced with CRIB at RIBF of RIKEN Nishina Center. The steady-state galactic abundance of the Al-26 radionuclide provides a unique window to the ongoing nucleosynthesis in the MIlky Way, as its decay along the galactic plane has...
