A Suzaku X-ray observation of one orbit of the supergiant fast X-ray transient IGR J16479-4514

L. Sidoli, P. Esposito, V. Sguera +6

We report on a 250 ks long X-ray observation of the supergiant fast X-ray transient (SFXT) IGR J16479-4514 performed with Suzaku in 2012 February. About 80% of the short orbital pe…
