New Timing Results of the X‐ray Binary Pulsar OAO 1657‐415

Abstract:

OAO 1657‐415 is an eclipsing X‐ray binary pulsar that has undergone several torque reversals throughout its long history of observation. We present a frequency history spanning nearly 19 years of observations from the Burst and Transient Source Experiment (BATSE) and from the Gamma‐Ray Burst Monitor (GBM). Orbital ephemerides of the pulsar system is obtained at several intervals throughout this history. With these ephemerides, statistically significant orbital decay is established.
