The radii of the inner and outer boundaries of the circumbinary habitable zone (CBHZ) and the radii of the circumbinary chaotic zone (CBCZ) have been calculated for close binary stars in the solar neighborhood with sufficient catalogue data. A subclass of binaries for which the CBCZ boundary is within the CBHZ boundaries (the CBCZ radius is larger than the inner CBHZ radius, but smaller than the outer CBHZ radius) has been identified for the first time: M4-V69, HATS551-027, EZ Aqr A–C, 38 Cas, HD 2070, HD 15064, HD 28394, HD 160346, and HD 181602. Since, according to present-day theories and observational data, the probability of finding planets at the CBCZ boundary is high, one might expect the presence of potentially habitable circumbinary planets in the planetary systems of the binary stars revealed in this way. For the stars CM Dra, WTS 19c-3-01405, and LP 661-13 the CBCZ radius is smaller than the radius of the inner CBHZ boundary, but planets may be present around them in outer stable orbits resonant with the orbits of planets near the CBCZ boundary. Therefore, all of the binaries of these types revealed for the first time are of considerable interest for future observations.

太阳附近的行星系行星系统：稳定性和可居住性

利用足够的目录数据，已经为太阳邻区中的近距离双星计算了可居住环带（CBHZ）的内边界和外边界的半径以及可混沌环带（CBCZ）的半径。首次识别出CBCZ边界在CBHZ边界内（CBCZ半径大于内部CBHZ半径但小于外部CBHZ半径）的二进制文件的子类：M4-V69，HATS551-027， EZ Aqr A–C，38 Cas，HD 2070，HD 15064，HD 28394，HD 160346和HD181602。由于根据当今的理论和观测数据，在CBCZ边界发现行星的可能性很高，因此，可能期望以这种方式揭示的双星恒星的行星系统中存在潜在宜居的外行星。对于明星CM Dra，在WTS 19c-3-01405和LP 661-13中，CBCZ半径小于内部CBHZ边界的半径，但是行星可能围绕它们出现在与CBCZ边界附近的行星轨道共振的外部稳定轨道周围。因此，首次公开的所有这些类型的二进制文件对于以后的观察都引起了极大的兴趣。
