论文摘要
我们报告了自最初发现以来的30 - 60年中，我们报告了五个中间极点（DQ Herculis，Ao Piscium，Fo Aquarii，V1223 Sagittarii和BG Canis Minoris）的详细历史。大多数人正在慢慢旋转，尽管有时会有长达数年的旋转发作。这支持了下面的磁白矮人接近自旋平衡的想法。除了约40颗恒星共享许多属性并取决于其强烈的X射线排放，还有一些旋转速度更快（P <80 s），其班级的成员仍然有疑问 - 并且他们逾期仔细研究。
We report the detailed history of spin-period changes in five intermediate polars (DQ Herculis, AO Piscium, FO Aquarii, V1223 Sagittarii, and BG Canis Minoris) during the 30-60 years since their original discovery. Most are slowly spinning up, although there are sometimes years-long episodes of spin-down. This is supportive of the idea that the underlying magnetic white dwarfs are near spin equilibrium. In addition to the ~40 stars sharing many properties and defined by their strong, pulsed X-ray emission, there are a few rotating much faster (P<80 s), whose membership in the class is still in doubt -- and who are overdue for closer study.
