Abstract

Our long-term goal is to develop a new supernova equation of state that meets the observational 2 M⊙ neutron star constraint and that includes quark matter. In this work, we perform a parameter scan to systematically investigate the hadron-quark phase transition in cold neutron stars using the state-of-the-art supernova equation of state HS(DD2) for the hadronic phase. We find neutron star configurations with maximum masses above 2 M⊙ and even above the maximum mass of HS(DD2). Our results show good agreement with other parameter scans.
