Abstract

THE 1.24 s X-ray pulses observed in the 2-20 keV region from Her X-1 are thought to arise from matter being accreted on to a rotating, magnetic neutron star. The pulse shape has been studied by several groups^1-3. More than 65% of the emission is concentrated in 0.4 of the duty cycle. The emission in this interval is usually double peaked, though it is sometimes single peaked¹ or asymmetrical^2,3. The pulse profile varies on time-scales of hours to days¹, and from pulse to pulse (my unpublished work with T. Chetim and R. Giacconi).
