Quark core formation in spinning-down pulsars
G. F. Marranghello, T. Regimbau, J. A. de Freitas Pacheco
Pulsars spin-down due to magnetic torque reducing its radius and increasing the central energy density. Some pulsar which are born with central densities close to the critical valu…
Determining the neutron star equation of state using the narrow-band gravitational wave detector Schenberg
G. F. Marranghello, J. C. N. de Araujo
We briefly review the properties of quasi-normal modes of neutron stars and black holes. We analyse the consequences of a possible detection of such modes via the gravitational wav…
Are Neutron-Rich Elements Produced in the Collapse of Strange Dwarfs ?
G. F. Marranghello, J. A. de Freitas Pacheco
The structure of strange dwarfs and that of hybrid stars with same baryonic number is compared. There is a critical mass (M~0.24M_sun) in the strange dwarf branch, below which conf…
Effects of Strong Magnetic Fields in Neutron Star and Gravitational Wave Emission
G. F. Marranghello
I review in this work the properties of nuclear and quark matter equation of state under the influence of a strong magnetic field. We analyse the results when they are applied to c…
Phase Transitions in Neutron Stars and Gravitational Wave Emission
G. F. Marranghello, C. A. Z. Vasconcellos, J. A. de Freitas Pacheco
We review the detectability of gravitational waves generated by oscillations excited during a phase transition from hadronic matter to deconfined quark-gluon matter in the core of…
A nuclear many-body theory at finite temperature applied to protoneutron star
Guilherme F. Marranghello, Cesar A. Z. Vasconcellos, Manfred Dillig
Thermodynamical properties of nuclear matter are studied in the framework of an effective many-body field theory at finite temperature, considering the Sommerfeld approximation. We…
