摘要:\( \leq \boldsymbol{\mathcal{O}}(100)\)]]> MeV/nucleon predominantly contributes to the total yields. Therefore, atomic cross sections in the low-energy range should be input accurately. We identify important seed nuclides for all p -nuclides. The contribution of CRN is significa...

摘要:44Ti is the short-live radioactive isotope with a half lifetime of 59 years. It can be only produced in the central regions of supernova explosions, so that its production will sensitively depend on supernova progenitors and explosion models. We have detected ...

摘要:The recent detection of gravitational waves and electromagnetic emissions from the binary neutron star merger GW170817 resulted in stringent limits concerning the masses and radii of the coalescing stars. These estimates complement ongoing measurements from pulsar timing and X-ra...

摘要:The 12C+12C fusion reaction at stellar energies, which is known as carbon burning in stars, plays an important role in stellar evolution. The astrophysically important energy range spans roughly from 1 to 3 MeV. The complication of molecular resonances in ...

摘要:Solving the hydrostatic structure of a self-gravitating system, stellar evolution simulation involves several input physics; a nuclear reaction network, thermal neutrino radiation, opacity, and so on. Moreover, continuous efforts have been devoted to deal with the effects of stel...

摘要:KISS (KEK Isotope Separation System) project aims at finding an astrophysical condition for synthesizing isotopes of heavy elements under a rapid neutron-capture ( r )-process, which forms the third peak in the solar abundance pattern. So far, we have performed measurements ...

摘要:Precision on primordial abundances, deduced from observations, have now reached the percent level for 4He and deuterium. Precision on big bang nucleosynthesis (BBN) predictions should, hence, reach the same level. The uncertainty on the 4He mass fraction is ...

摘要:In this paper, we study about the 7Li production in inhomogeneous Big-Bang Nucleosynthesis (IBBN). We assume that there are the high-density island at the BBN epoch. In IBBN model, the average values of 7Li can be lower than that of SBBN model if we select a...
