Consistent inference of neutron star bulk and crust properties and nuclear observables.
Time: 2:00 pm
Place: Join Zoom Meeting Meeting ID: 912 3071 4547
Speaker: Will Newton , Texas A&M
Abstract: We have entered the era of multi-messenger nuclear astrophysics,
bringing a host of astrophysical observations and nuclear experimental
data to collectively measure the properties of neutron star matter and
the nuclear force in neutron-rich systems. In order to combine disparate
data sets with meaningful uncertainty quantification, over the past
decade statistical inference techniques employing ensembles of
models of each observable have been increasingly employed. In order to
minimize systematic model uncertainty, where possible the same
underlying model should be used to construct neutron star and nuclear
models. We present an example of such an approach, using an
Energy-Density Functional to model bulk properties of neutron stars such
as the maximum mass, radii, tidal deformabilities and moments of
inertia, crust properties of neutron stars, and nuclear properties
including nuclear masses, neutron skins and dipole polarizabilities. In
particular, we argue that crust observables can help constrain both core
properties and nuclear observables when consistent ensembles of crust
models are used.
