Scope of the meeting

The workshop will bring together observational astrophysicists and nuclear physicists to develop an improved understanding of the equation of state over a wide range of densities. One of the key goals is to explore astrophysical and nuclear physics constraints for neutron star radii, and the implications for nuclear astrophysics.

Recent breakthroughs like the first detection of the gravitational wave signal of the neutron star merger as well as ongoing missions aiming at first direct neutron-star radius measurements using x-ray timing are expected to significantly enhance our theoretical understanding of neutron-rich matter under extreme conditions.

Complementary to these novel astrophysical constraints, significant progress has been achieved in recent years in constraining properties of dense matter based on microscopic calculations and nuclear interactions derived within chiral effective field theory. Such ab initio studies provide constraints for the nuclear symmetry energy, which can also be benchmarked against results from laboratory experiments. However, such studies are naturally limited to lower densities, up to about nuclear saturation density for neutron-rich systems. This limitation makes it necessary to combine these constraints with information from observations in order to obtain a comprehensive understanding of the equation of state over the full density range relevant for neutron stars.

Specifically, recent developments in the following fields will be discussed:

  • EOS from laboratory experiments
  • EOS from microscopic calculations
  • Electromagnetic and gravitational-wave observations for EOS constraints
