We calculate the expected effects on the spectral energy distributions and light curves in X-ray binary jets from eclipses by the donor stars. Jets will be eclipsed for all inclination angles, with just the height along the jet where the eclipse takes place being set by the orbital parameters. Typically, eclipses will lead to 5-10\% reductions in the jet emission over a range of a factor of few in wavelength with a periodic modulation. In ideal systems with high inclination angles, relatively even mass ratios, and modest jet speeds, the eclipses may be deeper. We discuss how eclipses can be used to measure binary system parameters, as well as the height of the bases of the jets. We also discuss how, with data sets that will likely require future facilities, more detailed tests of models of jet physics could be made, by establishing deviations from the standard recipes for compact conical flat spectrum jets, and by determining the ingress and egress durations of the eclipses and measuring the transverse size of the jets. We provide representative calculations of expectations for different classes of systems, demonstrating that the most promising target for showing this effect in the radio band are the longer period "atoll"-class neutron star X-ray binaries, while in the optical and infrared bands, the best candidates are likely to be the most edge-on black hole X-ray binaries. We also discuss the effects of the outer accretion disc eclipsing the inner jet.

X射线双星的射流和圆盘的日食是理解射流物理和双星参数的强大工具

我们计算了供体星日食对 X 射线双星喷流的光谱能量分布和光变曲线的预期影响。喷气机将在所有倾角下发生日食，只有沿喷气机发生日食的高度由轨道参数设置。通常，日食会导致射流发射在波长范围内通过周期性调制减少 5-10%。在具有高倾角、相对均匀的质量比和适度的喷射速度的理想系统中，日食可能更深。我们讨论日食如何用于测量双星系统参数，以及射流底部的高度。我们还讨论了如何使用可能需要未来设施的数据集对喷气物理学模型进行更详细的测试，通过建立与紧凑锥形扁平光谱射流标准配方的偏差，并确定日食的进出持续时间并测量射流的横向尺寸。我们提供了对不同类型系统的期望值的代表性计算，证明在无线电波段中显示这种效应的最有希望的目标是更长周期的“环礁”级中子星 X 射线双星，而在光学和红外波段，最好的候选者可能是最前沿的黑洞 X 射线双星。我们还讨论了外吸积盘遮住内射流的影响。我们提供了对不同类型系统的期望值的代表性计算，证明在无线电波段中显示这种效应的最有希望的目标是更长周期的“环礁”级中子星 X 射线双星，而在光学和红外波段，最好的候选者可能是最前沿的黑洞 X 射线双星。我们还讨论了外吸积盘遮住内射流的影响。我们提供了对不同类型系统的期望值的代表性计算，证明在无线电波段中显示这种效应的最有希望的目标是更长周期的“环礁”级中子星 X 射线双星，而在光学和红外波段，最好的候选者可能是最前沿的黑洞 X 射线双星。我们还讨论了外吸积盘遮住内射流的影响。
