Hybrid stars with large strange quark cores
Márcio Ferreira, Renan Câmara Pereira, Constança Providência
The possible existence of hybrid stars is studied using several multi-quark interaction channels. The hadronic phase consists of an equation of state (EoS) with presently accepted…
Hybrid stars from a constrained equation of state
Márcio Ferreira, Renan Câmara Pereira, Constança Providência
We determine, within a meta-model, the properties of the nuclear matter equation of state (EoS) that allow for a phase transition to deconfinement matter. It is shown that the prop…
Hybrid stars with large strange quark cores constrained by GW170817
Márcio Ferreira, Renan Câmara Pereira, Constança Providência
We analyze the impact of several multi-quark interaction channels on the properties of hybrid stars. Four and eight vector interactions were included in the NJL model to de…
Quark matter in light neutron stars
Márcio Ferreira, Renan Câmara Pereira, Constança Providência
Higher-order repulsive interactions are included in the three-flavor NJL model in order to describe the quark phase of an hybrid star. The effect of 4-quark and 8-quark vector-isos…
Neutron stars with large quark cores
Márcio Ferreira, Renan Câmara Pereira, Constança Providência
We describe charge-neutral neutron star matter in equilibrium using hybrid equations of state, where a first-order phase transition from hadronic to quark matter is realized. T…
Two-solar-mass hybrid stars: a two model description with the Nambu-Jona-Lasinio quark model
Renan Câmara Pereira, Pedro Costa, Constança Providência
Hybrid stars with a quark phase described by the NambuJona-Lasinio model are studied. The hadron-quark model used to determine the stellar matter equation of state favors the ap…
