Detection of X-ray Emission from the PSR 1259-63/SS2883 Binary System . ... Abstract Non-pulsed but variable X-ray emission has been detected from the binary system containing the radio pulsar PSR 1259-63 during two pointed ROSAT observations, taken five months apart. This 47.7 ms radio pulsar is in a highly eccentric (e~0.85) binary system with the 10-15 Msun Be-star SS2883. ... The system may be the progenitor of the more slowly rotating Be X-ray binary pulsar systems. simonj@physics.usyd.edu.au ...

Over the last year, the greatest development in pulsar research at the Arecibo Observatory has been the start of the main ALFA pulsar survey. ... A great example of the new, compact binary systems that ALFA can find is PSR J1906+0746. This is a 144-ms pulsar in a binary system with an orbital period just under 4 hours and a massive companion. ... One particularity of this system is that it is about 1000 times younger than the double pulsar , i.e., it is by far the youngest binary system known. ...

After being first recognised as a distinct category of Gamma-Ray Bursts (GRBs), the progenitors of short GRBs have remained highly elusive although we have long suspected that they are compact binary mergers. ... The compact binary merger progenitor is typically thought to produce a black hole central engine. However, we have now identified prolonged energy injection in short GRB lightcurves that is inconsistent with the expected black hole central engine. ...
