Do Delta baryons play a role in neutron stars?
The presence of exotic hadrons, such as hyperons and Δ isobars, in the dense nuclear matter in their cores has been shown to produce important changes in the properties of neutron stars. Within the quark-meson coupling model, we show that the many-body forces generated by the change in the internal...
