    Asanosuke Jinno (Kyoto University)
    5/15/25, 1:00 PM

    A unified approach integrating heavy-ion collisions, other nuclear experiments, and neutron stars with the modern nuclear force
    from chiral effective field theory (chiral EFT) has provided valuable insights into the properties of the equation of state of dense matter. For a microscopic description of dense matter, such an approach should be performed also for the hyperon sector, particularly...

  9. 8. Role of Hyperon Interactions in Neutron Stars and Supernova Cores
    Dr Hajime Togashi (Kyoto University)
    5/15/25, 1:35 PM

    The presence of hyperons in high-density astrophysical environments, such as supernova cores and neutron stars, significantly affects their equation of state (EoS) and overall structure. At extreme densities and temperatures, hyperons are expected to emerge, softening the EoS and influencing the evolution of (proto) neutron stars. However, this softening leads to the so-called hyperon puzzle,...
