| Research Abstract |
We have investigated structure and properties of nuclear matter in supernovae and neutron stars. During first-order phase transitions such as liquid-gas, kaon condensation, and hadron-quark transition, matter exhibit exotic structures called "pasta", which influences the equation of state (EOS) and particle fraction of matter. We have successfully reproduced radii and masses of neutron stars using the obtained EOS.
