Quantifying the Information Gain from Future High-Precision Radius Measurements for Identifying Twin Neutron Stars

Twin neutron stars (NSs), characterized by identical gravitational masses but different radii, are among the most promising astrophysical signatures of a strong first-order hadron--quark phase transition in supradense matter.
