Description
As the number of unexplained mass–radius measurements of compact objects in the neutron star regime grows, systematically comparing scenarios beyond standard neutron star — i.e., assuming strongly interacting matter and general relativity — becomes increasingly important. In this work, we perform a Bayesian analysis of different scenarios capable of explaining current and future measurements that are in tension with purely standard neutron star configurations.
Among the scenarios considered, we focus on configurations with gravitationally coupled dark matter. In particular, adopting a general ansatz for bosonic dark matter, we map the regions of the mass–radius diagram that are inaccessible to standard neutron stars. We identify the range of mass–radius measurements that would provide strong evidence for the presence of a dark matter halo or a dark matter core.
