论文摘要
在我们的太阳系中，巨大的外行星在质量和角动量方面都占主导地位，但是当前有4000多个行星中，很少有这样的行星在当前确认的系外行星中，而且这些行星都没有准确确定的密度。在这里，我检查了从LSST深入钻井场预期的单个透射事件的检测率，该行星的周期为2-25年。使用保守的检测标准，我预计该项目的10年期间将有3-30个此类检测，尽管将检测与误报区分开可能会挑战。但是，这些少数检测对于理解系外行星系统的形成，动力学和多样性可能具有很大的价值。
In our solar system massive outer planets dominate in terms of both mass and angular momentum, but few such planets are among the more than 4000 currently confirmed exoplanets, and none of these have accurately determined densities. Here I examine the detection rate of single-transit events anticipated from the LSST deep drilling fields for such planets with periods of 2 - 25 years. Using conservative detection criteria, I anticipate 3-30 such detections over the 10-year period of the project, though distinguishing detections from false positives may prove challenging. However, these few detections are likely to be of great value in understanding the formation, dynamics, and diversity of exoplanet systems.
