[GA189] PSR J2032+4127, the counterpart of TeV J2032+4130? Multiwavelength Monitoring of the Approach to Periastron

PSR J2032+4127 has recently been identified as being in a highly eccentric, long period (45-50 years) binary with the Be star MT91 213. Periastron is due to occur in November 2017 and this rare occurrence has prompted a multiwavelength monitoring campaign to determine if the system is a gamma-ray binary, and, if so, to study what would be only the second gamma-ray binary with a known compact object. Located close to TeV J2032+4130 this could also explain the hitherto unknown origin of the very high energy gamma-ray emission from that region. As part of this monitoring, observations are being conducted by Swift, Fermi-LAT and VERITAS. We present the status of those observations, preliminary results and the plan for continued monitoring through periastron.
