Identifying which systems are more likely to host an imageable planet can play an important role in the construction of an optimized target list for future direct imaging missions, such as the planned Coronagraph Instrument (CGI) technology demonstration for the Nancy Grace Roman Space Telescope. For single-planet systems, the presence of an already detected exoplanet can severely restrict the target’s stable region and should therefore be considered when searching for unknown companions. To do so, we first analyze the performance and robustness of several two-planet stability criteria by comparing them with long-term numerical simulations. We then derive the necessary formulation for the computation of ( a , R ) analytic stability maps, which can be used in conjunction with depth-of-search grids in order to define the stable-imageable region of a system. The dynamically stable completeness (i.e., the expected number of imageable and stable planets) can then be calcul...

用于成像优先级的未知系外行星同伴的解析稳定性图

在为未来的直接成像任务（例如计划中的南希·格雷斯·罗马太空望远镜的电晕仪（CGI）技术演示）的优化目标清单的构建中，确定哪些系统更可能拥有可成像的行星可以发挥重要作用。对于单行星系统，已经检测到的系外行星的存在会严重限制目标的稳定区域，因此在搜索未知同伴时应予以考虑。为此，我们首先将几个两行星稳定性标准与长期数值模拟进行比较，以分析其性能和鲁棒性。然后，我们得出计算（a，R）解析稳定性图的必要公式，可以与搜索深度网格结合使用，以定义系统的稳定可成像区域。然后可以计算动态稳定的完整性（即，可成像和稳定的行星的预期数量）...
