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.

隐藏的世界:多行星系统中未检测行星的动力学架构预测以及在 TESS 系统中的应用

多行星系统为系外行星科学提供了丰富的信息,但我们对行星结构的理解并不完整。进一步探测这些系统将提供对轨道结构和形成路径的深入了解。在这里,我们提出了一个模型,通过人口统计预测这些系统中以前未被发现的行星。该模型同时考虑了凌日和非凌日行星,并且可以测试添加不止一颗行星。我们的测试表明,该模型的轨道周期预测对于系统架构中几个百分点的扰动具有鲁棒性,远大于当前的不确定性。将其应用于 TESS 的多行星系统,根据预测的过境深度和概率,提供优先目标列表,
