A strongly magnetic neutron star in the SMC Be/X-ray binary SXP 1062 ?    [PDF]

S. B. Popov, R. Turolla
The newly discovered Be/X-ray binary in the Small Magellanic Cloud, SXP 1062, provides the first example of a robust association with a supernova remnant (SNR). The short age estimated for the SNR qualifies SXP 1062 as the youngest known source in its class. As such, it allows to test current models of magneto-rotational evolution of neutron stars in a still unexplored regime. Here we discuss possible evolutionary scenarios for SXP 1062. Our results favor the presence of a neutron star with an initial large magnetic field, typically in excess of ~ 1e14 G, which then decayed to ~ 1e13 G.
