OSSE Observations of X-Ray Pulsars

Abstract

We report on OSSE observations of the Be binary pulsars A0535+26, GRO J1008-57, and 4U 0115+63 at energies above 50 keV. The spectra are generally thermal, with exponential folding energies of 15-25 keV, and no evidence for hard power-law tails. We have clearly detected a strong cyclotron absorption line at 110 keV from A0535+26 [1], and we find a suggestion of an absorption line near 90 keV from GRO J1008-57.
