abstract = "We investigate the possibility of some Soft Gamma-ray Repeaters
(SGRs) and Anomalous X-ray Pulsars (AXPs) could be described as
rotation-powered neutron stars (NSs). The analysis was carried out
by computing the structure properties of NSs, and then we focus on
giving estimates for the surface magnetic field using both
realistic structure parameters of NSs and a general relativistic
model of a rotating magnetic dipole. We show that the use of
realistic parameters of rotating neutron stars obtained from
numerical integration of the self-consistent axisymmetric general
relativistic equations of equilibrium leads to values of the
magnetic field and radiation efficiency of SGRs/AXPs very
different from estimates based on fiducial parameters. This
analysis leads to a precise prediction of the range of NS masses,
obtained here by making use of selected up-to-date nuclear
equations of state (EOS). We show that 40% (nine) of the entire
observed population of SGRs and AXPs can be described as canonical
pulsars driven by the rotational energy of neutron stars, for
which we give their possible range of masses. We also show that if
the blackbody component in soft X-rays is due to the surface
temperature of NSs, then 50% of the sources could be explained as
ordinary rotation-powered pulsars. Besides, amongst these sources
we find the four SGRs/AXPs with observed radio emission and six
that are possibly associated with supernova remnants (including
Swift J1834.9-0846 as the first magnetar to show a surrounding
wind nebula), suggesting as well a natural explanation as ordinary
pulsars.",
