Experimental study of symmetry energy
Nuclear weak rates relevant to the study of astrophysical processes in stars are evaluated with the use of shell-model Hamiltonians that prove to be successful in describing Gamow-Teller (GT) and spin-dipole (SD) strengths in nuclei. Electron-capture and β-decay rates in stellar environments induced by GT transitions in sd-shell and pf-shell are applied to study nuclear URCA processes in...
Quasi-periodic oscillations (QPOs) observed in giant flare from the magnetar, which is a strongly magnetized neutron star, are crucial information for extracting the neutron star properties. To theoretically explain the QPOs newly observed in GRB 200415A, we systematically examine the crustal torsional oscillations. Then, we find that the observed QPOs can be identified with several overtone...
