论文摘要
我们提出了相互分辨的光谱，光度法和圆形光谱法的圆形光谱法。使用内部投影的最强发射线的多普勒断层扫描揭示了三个发射区域的存在：从次级恒星的辐射面，弹道流和螺纹区域以及磁性限制的增生流。总强度频谱显示出较大的发射特征和蓝色上升的连续体。循环极化光谱显示出三个回旋发射谐波在$ \ sim $4500Å，6000Å和7700Å中的存在，分别对应于谐波数4、3和2。这些特征在日食之前是主导的，并且在日食之后消失。谐波与$ \ sim $ 57毫克的磁场强度一致。我们还提出了相位分辨的圆形和线性光极化法，以补充日食时代周围的光谱法。 Meerkat无线电观察结果显示出一个微弱的来源，其峰值通量密度为30.7 $ \ pm $ 5.4 $ $ $ $ $ $ $ jy/beam/beam在1.28 GHz的位置，在UZ的位置。
We present phase-resolved spectroscopy, photometry and circular spectropolarimetry of the eclipsing polar UZ Fornacis. Doppler tomography of the strongest emission lines using the inside-out projection revealed the presence of three emission regions: from the irradiated face of the secondary star, the ballistic stream and the threading region, and the magnetically confined accretion stream. The total intensity spectrum shows broad emission features and a continuum that rises in the blue. The circularly polarized spectrum shows the presence of three cyclotron emission harmonics at $\sim$4500 Å, 6000 Å and 7700 Å, corresponding to harmonic numbers 4, 3, and 2, respectively. These features are dominant before the eclipse and disappear after the eclipse. The harmonics are consistent with a magnetic field strength of $\sim$57 MG. We also present phase-resolved circular and linear photopolarimetry to complement the spectropolarimetry around the times of eclipse. MeerKAT radio observations show a faint source which has a peak flux density of 30.7 $\pm$ 5.4 $μ$Jy/beam at 1.28 GHz at the position of UZ For.
