Abstract (from CDS):

The High Mass X-ray Binary Pulsar Centaurus X-3 was observed by the BeppoSAX satellite during 1997 February 17, while the system was in a high-luminosity (Lx=4.3x1037erg/s) post-egress state. In this Letter we report the detection of an absorption-like feature, centered at ∼28keV, in the broad band phase averaged spectrum. Interpreting the feature as due to cyclotron resonant scattering, we estimate the magnetic field strength close to the surface of the neutron star to be B~(2.4-3.0)x1012G.
