"Exploring the Quark Matter Mystery at the Heart of Super-Dense Neutron Stars"

A new study published in Nature Communications suggests that the most massive neutron stars, with masses over twice that of the sun, have a high likelihood (80%-90%) of containing quark cores. This conclusion was reached using Bayesian statistics applied to observational data on neutron star mass and size, rather than solely relying on the complex Tolman-Oppenheimer-Volkoff (TOV) equation. While the data set is currently limited, more observations in the future could help confirm the presence of quark matter and identify the transition point between regular neutron stars and those with quark cores.
