[53.04] Comparing Torque and Luminosity in Transient X-ray Pulsars

M. Saia, M. J. Stark (Lafayette College)

We have observed several transient outbursts of X-ray pulsars with the Rossi X-Ray Timing Explorer. We have begun to study them to explore the relationship between the pulsar period derivative (related to the torque on the star) and the X-ray luminosity (related to the mass accretion rate). Results from the first of these stars are presented here. We track these sources through large variations in the torque, often including a change in the sign of the torque.
