White dwarfs with a surface electrical charge distribution: Equilibrium and stability
G. A. Carvalho, José D. V. Arbañil, R. M. Marinho +1
The equilibrium configuration and the radial stability of white dwarfs composed of charged perfect fluid are investigated. These cases are analyzed through the results obtained fro…
Equilibrium and stability of charged strange quark stars
José D. V. Arbañil, M. Malheiro
The hydrostatic equilibrium and the stability against radial perturbation of charged strange quark stars composed of a charged perfect fluid are studied. For this purpose, it is co…
A different nature between the radio AXPs in comparison to the others SGRs/AXPs
J. G. Coelho, M. Malheiro
SGRs/AXPs are considered a subclass of pulsars powered by magnetic energy and not by rotation, as normal radio pulsars. They are understood as strongly magnetized neutron star, wit…
Dynamical instability of white dwarfs and breaking of spherical symmetry under the presence of extreme magnetic fields
J. G. Coelho, R. M. Marinho, M. Malheiro +4
Massive, highly magnetized white dwarfs with fields up to G have been observed and theoretically used for the description of a variety of astrophysical phenomena. Ultramagne…
