标题： Eclipse Mapping of the Accretion Stream in UZ Fornacis

摘要： 我们提出了一种新方法，可以从观测到的光变曲线中绘制AM Herculis系统的吸积流表面亮度图。 对该算法的广泛测试表明，对于信噪比>5的数据，它可以可靠地再现流的强度分布。 作为首次应用，我们使用HST FOS高态光谱绘制了极移天龙座UZ For中的Civ λ1550吸积流发射。 我们在吸积流中发现了三个主要的发射区域：（1）在吸积流的弹道部分，（2）在靠近初级吸积斑点的磁引导流中，以及（3）在停滞区上方的磁引导流中。 显示英文摘要

摘要： We present a new method to map the surface brightness of the accretion streams in AM Herculis systems from observed light curves. Extensive tests of the algorithm show that it reliably reproduces the intensity distribution of the stream for data with a signal-to-noise ratio >5. As a first application, we map the accretion stream emission of Civ lambda 1550 in the polar UZ Fornacis using HST FOS high state spectra. We find three main emission regions along the accretion stream: (1) On the ballistic part of the accretion stream, (2) on the magnetically funneled stream near the primary accretion spot, and (3) on the magnetically funneled stream at a position above the stagnation region.
