摘要
HESS J0632+057 是迄今为止已知的唯一一颗天空位置允许南北半球地面观测站同时进行观测的伽马射线双星。在此，我们报告了利用 VERITAS 和 H.E.S.S. 切伦科夫望远镜以及 Swift X 射线卫星对 HESS J0632+057 进行的长期观测结果，时间跨度从 2004 年至 2012 年，覆盖了该系统的大部分轨道。研究发现甚高能（VHE）辐射具有变化性，并与 X 射线能段的辐射相关。从 X 射线数据集中推导出的轨道周期为 天，与先前结果 天相容。VHE 光变曲线在接近 0.3 的轨道相位处（即过近星点后约 100 天）显示出明显的最大值，这与 X 射线辐射的周期性增强相吻合。此外，对 TeV 数据的分析首次显示在 0.6--0.9 的轨道相位处存在统计显著性（）的探测。我们在该系统近期获得的星历表背景下，讨论了所获得的伽马射线和 X 射线光变曲线以及这两个能段源辐射的相关性。我们将我们的结果与其他伽马射线双星的报道结果进行了比较。
