Evidence for a multipolar magnetic field in SGR J1745-2900 from X-ray light-curve analysis
Rafael C. R. de Lima, Jaziel G. Coelho, Jonas P. Pereira +2
SGR J1745-2900 was detected from its outburst activity in April 2013 and it was the first soft gamma repeater (SGR) detected near the center of the Galaxy (Sagittarius A). We u…
Gravitational waves from SGRs and AXPs as fast-spinning white dwarfs
Manoel F. Sousa, Jaziel G. Coelho, José C. N. de Araujo
Gravitational waves (GWs) emission due to magnetic deformation mechanism is applied for Soft Gamma Repeaters (SGRs) and Anomalous X-Ray Pulsars(AXPs), described as fast-spinning an…
Gravitational Waves From Pulsars Due To Their Magnetic Ellipticity
José C. N. de Araujo, Jaziel G. Coelho, Samantha M. Ladislau +1
We discuss some aspects of de Araujo, Coelho & Costa (2016, 2017) concerning the role of a time dependent magnetic ellipticity on the pulsars' braking indices and on the putative g…
Born-Infeld magnetars: larger production of gravitational waves due to larger toroidal magnetic fields
Jonas P. Pereira, Jaziel G. Coelho, Rafael C. R. de Lima
We discuss some aspects of Pereira et al. (2018) concerning magnetars described by nonlinear theories of the electromagnetism and make the case for the Born-Infeld Lagrangian. We f…
