论文摘要
我们提供了HD79210和HD79211的HARPS-N光谱仪的高精度径向速度（RV），这是重力结合的二进制系统的两个M0V成员。我们检测到一个$ 24.421^{+0.016} _ { - 0.017} $ DAME $ 24.421^{ - 0.017} $ DAME在HD79211中的$ 24.421^{+0.016}候选者，在这些HARPS-N RVS中，$ 24.421^{+0.016}_。使用HARPS-N，CARMENES和HIRES RVS总计25年，我们进一步将行星候选参数改进到$ p = 24.422 \ pm0.014 $ days，$ k = 3.19 \ pm0.27 $ m/s，$ m $ sin $ $ sin $ sin $ i = 10.6 \ pm 1.2 m_ \ pm 1.2 m_ $ $ $ $ aup $ au = 0.142和0.142＆au = 0.142。我们在HD79211的数据中找不到任何其他行星候选信号，也没有在HD79210中找到任何行星候选信号。该系统增加了与M DWARF成员在二进制中检测到的系外行星的数量，并用作恒星二进制行星形成的案例研究。
We present high-precision radial velocities (RVs) from the HARPS-N spectrograph for HD79210 and HD79211, two M0V members of a gravitationally-bound binary system. We detect a planet candidate with a period of $24.421^{+0.016}_{-0.017}$ days around HD79211 in these HARPS-N RVs, validating the planet candidate originally identified in CARMENES RV data alone. Using HARPS-N, CARMENES and HIRES RVs spanning a total of 25 years, we further refine the planet candidate parameters to $P=24.422\pm0.014$ days, $K=3.19\pm0.27$ m/s, $M$ sin $i = 10.6 \pm 1.2 M_\oplus$, and $a = 0.142 \pm0.005$ au. We do not find any additional planet candidate signals in the data of HD79211 nor do we find any planet candidate signals in HD79210. This system adds to the number of exoplanets detected in binaries with M dwarf members, and serves as a case study for planet formation in stellar binaries.
