Zusammenfassung:
We investigate the remnant neutron star mass, in particular the minimum mass.
We perform advanced stellar evolution calculations and neutrino-radiation
hydrodynamics simulations for core-collapse supernova explosions based on the
standard astrophysical scenarios. We find that from low-mass carbon-oxygen
cores which form sufficiently massive iron cores that eventually collapse, the
remnant neutron stars after supernova explosion are as light as 1.17 $M_\odot$,
which is compatible with the lowest mass of the neutron star precisely measured
in a binary system of PSR J0453+1559.
