标题： The Orbital Period of Intermediate Polar 1WGA J1958.2+3232

摘要： 报告了新发现的中间极性变星 1 WGA 1958.2+3232 的轨道周期 4.36 小时。 轨道周期是从时间分辨的光度和光谱观测中推导出来的。 我们还确认了白矮星的 733 秒自转周期与 X 射线脉动一致，并且能够区分出光曲线中的拍频。 从光谱观测中检测到来自发射谱线的强轨道周期调制。 它们显示出吸积盘边缘存在一个明亮的热点。 这个最近发现的中间极性变星的参数被确定下来。 显示英文摘要

摘要： The detection of the orbital period of 4.36his reported for the new Intermediate Polar 1 WGA 1958.2+3232. The orbital period was derived from time-resolved photometric and spectral observations. We also confirmed the 733 sec spin period of the White Dwarf consistent with the X-ray pulsations and were able to distinguish the beat period in the light curve. Strong modulations with orbital period are detected in the emission spectral lines from spectral observations. They show the presence of a bright hot spot on the edge of the accretion disk. The parameters of this recently discovered Intermediate Polar are determined.
