I also contribute to our understanding of two newly discovered and heavily-absorbed pulsars (neutron stars with strong magnetic fields) by determining the orbital parameters of the systems through pulse timing analysis. Orbital phase-resolved spectroscopy of one source revealed evidence for an qaccretion wakeq trailing the pulsar through its orbit, showing that X-rays emanating from the surface can ionize the stellar wind in its vicinity.4.3.1 Introduction In principle, any type of variability can be used to determine the distance to a variable X-ray source. ... Sharp and temporary intensity changes, such as that produced by type I bursts or gamma-ray bursts (GRBs), produce aanbsp;...
