General-purpose equations of state for hadron-quark matter: first application to accretion-induced phase transitions in neutron stars
János Takátsy, Henrique Gieg, Tim Dietrich
Strong first-order phase transitions in the cores of neutron stars (NSs) can have profound implications for astrophysical observables, however, their existence remains an open ques…
Investigating the influence of the full-kinematics treatment for charged-current processes in binary neutron star mergers
Ramon Jaeger, Henrique Gieg, Tim Dietrich
Weak interactions are fundamental in the merger of binary neutron stars (BNS). They provide cooling, change the composition of matter outflows, and can lead to significant secular…
