Abstract
  • Millisecond pulsar B1744-24A (Ter5A) in globular cluster Terzan 5 belongs to the one of the few 'windy' binary systems, with unbound material escaping from the companion star and interacting with the pulsar's magnetosphere. In this work we used two decades of timing data to trace the evolution of the pulsar's spin and orbital parameters. Also, Ter5A appears to emit strong wide single pulses, with energies 30 or more times the mean pulse energy, with widths comparable to that of the average profile. These pulses occur preferentially shortly before and after the pulsar is obscured by the unbound material from the companion star.
