Constraints on high density equation of state from maximum neutron star mass
Márcio Ferreira, Constança Providência
The low density nuclear matter equation of state is strongly constrained by nuclear properties, however, for constraining the high density equation of state it is necessary to reso…
Crust-core transition of a neutron star: effect of the temperature under strong magnetic fields
Márcio Ferreira, Aziz Rabhi, Constança Providência
The effect of temperature on the crust-core transition of a magnetar is studied. The thermodynamical spinodals are used to calculate the transition region within a relativistic mea…
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…
Effect of the crust on neutron star empirical relations
Márcio Ferreira, Constança Providência
We analyze how the crust equation of state affects several neutron star properties and how it impacts on possible constraints inferred from astrophysical observations. Using three…
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…
