PSR J2032 +4127,TeV J2032 +4130的对应物?临近近星点的多波长监测

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

Ralph Bird

摘要:

PSR J2032+4127最近被发现是一个长周期(45-50年)双星,与Be星MT 91 213在一个高偏心轨道上。近日星将于2017年11月发生,这一罕见的事件促使多波长监测活动,以确定该系统是否是伽马射线双星,如果是的话,研究什么将是已知紧凑物体的第二个伽马射线双星。在与TeV J2032+4130相同的方向上,来自这个双星系统的伽马射线发射可能与来自该区域的扩展的非常高能量的伽马射线发射有关。作为监测的一部分,Swift、Fermi-LAT和VERITAS正在进行观测。我们介绍了这些观测的现状、初步结果和通过近星点继续监测的计划。

英文摘要:

PSR J2032+4127 has recently been identified as being in a long period (45-50 years) binary in a highly eccentric orbit 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. In the same direction as TeV J2032+4130, gamma-ray emission from this binary system could be related to the extended 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.
