Research in theoretical nuclear astrophysics

My research group studies how neutron star observations can be used to understand how neutrons and protons interact and how nuclear physics plays a role in astrophysical objects and processes. Recently, we have

  • determined how the equation of state and superfluid nature of dense matter is determined by neutron star observations,
  • showed how tidal deformabilities are modified by strong phase transitions,
  • and combined modern theoretical results on neutron matter and neutron star observations to make predictions for neutron star tidal deformabilities for LIGO.
