论文摘要
多行星系统为系外行星科学提供了大量信息，但是我们对行星体系结构的理解是不完整的。进一步探索这些系统将提供有关轨道架构和地层途径的洞察力。在这里，我们提出了一个模型，可以通过人口统计数据预测这些系统中未发现的行星。该模型考虑了过境和非传输行星，并且可以测试多个行星的添加。我们的测试表明，该模型的轨道周期预测对系统体系结构的扰动是强大的，该轨道构建的顺序比当前的不确定性大得多，要大得多。将其应用于TESS的多行星系统，根据预测的过境深度和概率，为档案搜索以及指导基于地面的后续观测值狩猎隐藏行星提供了优先的目标列表。
Multi-planet systems produce a wealth of information for exoplanet science, but our understanding of planetary architectures is incomplete. Probing these systems further will provide insight into orbital architectures and formation pathways. Here we present a model to predict previously undetected planets in these systems via population statistics. The model considers both transiting and non-transiting planets, and can test the addition of more than one planet. Our tests show the model's orbital period predictions are robust to perturbations in system architectures on the order of a few percent, much larger than current uncertainties. Applying it to the multi-planet systems from TESS provides a prioritized list of targets, based on predicted transit depth and probability, for archival searches and for guiding ground-based follow-up observations hunting for hidden planets.
