Dynamical constraints on the companion mass from pulsar timing and cyclotron line confirmation in the SFXT IGR J16418-4532
Supergiant Fast X-ray Transients (SFXTs) exhibit extreme X-ray variability on short timescales of minutes to hours, driven by accretion processes that are still poorly understood. IGR J16418–4532 is an intermediate SFXT in which X-ray pulsations have been detected and which has been proposed as a candidate cyclotron...
