论文摘要
SETI椭圆形是一种基于接收信号同步与明显天文事件的信号的策略来确定技术签名观测值的几何方法。从盖亚（Gaia）到附近恒星的精确距离使约束椭圆形穿越时间成为可能。在这里，我们探讨了使用附近恒星的Gaia目录在SN 1987a Seti Ellipsoid上选择目标的实用性，以及由278个古典Novae定义的椭圆形。 SN 1987a SETI椭圆形内的100个PC样品中只有不到8％的恒星，这意味着附近的绝大多数恒星仍然是随着时间的流逝监测的可行目标。我们发现，在100 pc的体积中，平均每年734颗星将与SN 1987a的椭圆形相交，而与盖亚的距离不确定性的人中约有10％比0.1 lyly更好。
The SETI Ellipsoid is a geometric method for prioritizing technosignature observations based on the strategy of receiving signals synchronized to conspicuous astronomical events. Precise distances to nearby stars from Gaia makes constraining Ellipsoid crossing times possible. Here we explore the utility of using the Gaia Catalog of Nearby Stars to select targets on the SN 1987A SETI Ellipsoid, as well the Ellipsoids defined by 278 classical novae. Less than 8% of stars within the 100 pc sample are inside the SN 1987A SETI Ellipsoid, meaning the vast majority of nearby stars are still viable targets for monitoring over time. We find an average of 734 stars per year within the 100 pc volume will intersect the Ellipsoid from SN 1987A, with ~10% of those having distance uncertainties from Gaia better than 0.1 lyr.
