On the nature of some SGRs and AXPs as rotation-powered neutron stars
Jaziel G. Coelho, D. L. Cáceres, R. C. R. de Lima +3
We investigate the possibility that some SGRs/AXPs could be canonical rotation-powered pulsars using realistic NS structure parameters instead of fiducial values. We show that real…
Thermal X-ray emission from massive, fast rotating, highly magnetized white dwarfs
D. L. Caceres, S. M. de Carvalho, J. G. Coelho +2
There is solid observational evidence on the existence of massive, , highly magnetized white dwarfs (WDs) with surface magnetic fields up to G. We sho…
Gravitational Waves from Pulsars and Their Braking Indices: The Role of a Time Dependent Magnetic Ellipticity
José C. N. de Araujo, Jaziel G. Coelho, César A. Costa
We study the role of time dependent magnetic ellipticities () on the calculation of the braking index of pulsars. Moreover, we study the consequences of such a on th…
Gravitational waves from pulsars in the context of magnetic ellipticity
José C. N. de Araujo, Jaziel G. Coelho, César A. Costa
In one of our previous articles we have considered the role of a time dependent magnetic ellipticity on pulsars' braking indices and on the putative gravitational waves these objec…
Gravitational waves from pulsars with measured braking index
Jose C. N. de Araujo, Jaziel G. Coelho, Cesar A. Costa
We study the putative emission of gravitational waves (GWs) in particular for pulsars with measured braking index. We show that the appropriate combination of both GW emission and…
The influence of quantum vacuum friction on pulsars
Jaziel G. Coelho, Jonas P. Pereira, José C. N. de Araujo
We firstly revisit the energy loss mechanism known as quantum vacuum friction (QVF), clarifying some of its subtleties. Then we investigate the observables that could easily differ…
Magnetars and White Dwarf Pulsars
Ronaldo V. Lobato, Manuel Malheiro, Jaziel G. Coelho
The Anomalous X-ray Pulsars (AXPs) and Soft Gamma-ray Repeaters (SGRs) are a class of pulsars understood as neutron stars (NSs) with super strong surface magnetic fields, namely $B…
