利用Pichardo等人的结果，我们确定了行星(或盘)可以在双星系统周围的稳定轨道上生存的动力稳定区域。我们对太阳附近161颗已知轨道参数的双星进行了这项研究。此外，作为对Pichardo等人的近似的检验，我们用数值方法构造了具有已知轨道参数和已确认行星的五个双星系统的圆盘(不变环)：HIP 10138、HIP 4954、HIP 67275、HIP 116727和开普勒16。在每一种情况下，报告的行星位置都在我们计算的稳定区域内。这项研究旨在为寻找具有已知轨道参数的双星系统周围的行星提供指导，因为我们的方法为稳定区域定义了精确的界限，在那里可能已经建立了圆盘和形成了行星。
Using the results of Pichardo et al., we determine regions of dynamical stability where planets (or discs in general) could survive in stable orbits around binary stellar systems. We produce this study for 161 binary stars in the solar neighbourhood with known orbital parameters. Additionally, we constructed numerically the discs (invariant loops) around five binary systems with known orbital parameters and with confirmed planets: HIP 10138, HIP 4954, HIP 67275, HIP 116727 and Kepler 16, as a test to the approximation of Pichardo et al. In each single case, the reported position of the planets lies within our calculated stability regions. This study intends to provide a guide in the search for planets around binary systems with well-known orbital parameters, since our method defines precise limits for the stable regions, where discs may have established and planets formed.
