In the context of the program Global Architecture of Planetary Systems (GAPS), we have performed radial velocity monitoring of the metal-poor star HIP 11952 on 35 nights over about 150 days using the newly installed high resolution spectrograph HARPS-N at the TNG and HARPS at ESO 3.6m telescope. The radial velocities show a scatter of 7 m/s, compatible with the measurement errors for such a moderately warm metal-poor star (Teff = 6040+-120K; [Fe/H] =-1.9+-0.1). We then exclude the presence of the two giant planets with periods of 6.95+-0.01 d and 290.0+-16.2 d and radial velocity semi-amplitudes of 100.3+-19.4 m/s and 105.2+-14.7 m/s, respectively, which had recently been announced. This result is important considering that HIP 11952 was thought to be the most metal-poor star hosting a planetary system with giant planets, thus challenging some models of planet formation.

我们提出了20年的径向速度（RV）测量的M1矮G115 A，结合5年的密集RV监测与HARPS-N摄谱仪与15年的档案HIRES/凯克RV数据。我们进行MCMC为基础的RV时间序列的分析，包括高斯过程（GP）的方法来描述恒星活动引起的RV变化。我们的分析证实了开普勒性质，并改进了11.44天周期的超级地球Gl 15 A\，b的轨道解，将其振幅减小到$1.68^{+0.17}_{-0.18}$ m s $^{-1}$（$M \sin i = 3.03^{+0.46}_{-0.44}$ M $_\oplus$），并成功地模拟了组合RV数据集中的长期趋势，其依据的是具有大约7600天的周期和$2.5^{+1.3}_{-1.0}$ m s $^{-1}$的幅度的开普勒轨道，对应于超海王星质量（$M \sin i = 36^{+25}_{-18}$ M $_\oplus$）行星伴星。通过详细的数值模拟，我们还讨论了G1 15 A行星系与大分离伴星G1 15 B之间Lidov-Kozai相互作用的可能结果，并讨论了G1 15 A的轨道构型.为了改善动力学分析的结果，我们推导出一个新的轨道解的双星系统，结合我们的RV测量和天体测量数据从WDS目录。Lidov-Kozai偏心率分析表明，Gl 15 B对Gl 15 A行星系有很强的影响，它可以产生与观测到的$75^\circ$和$90^\circ$…

我们提出了完整的贝叶斯统计分析的HARPS-N红矮星系外行星调查（HADES），监测径向速度的大样本M矮星与HARPS-N在TNG，在过去的6年。这些目标是在从M0到M3的狭窄光谱类型范围内选择的，$0.3$ M $_\odot < M_\star < 0.71$ M $_\odot$，目的是研究围绕一个定义明确的宿主恒星的行星群。我们利用贝叶斯统计，得出一个准确的估计的可检测性功能的调查。我们的分析还包括高斯过程方法的应用，以考虑恒星活动引起的径向速度变化，并提高检测限，周围的最观测和最活跃的目标。马尔可夫链蒙特卡罗和高斯过程技术，我们在这项分析中应用已被证明是非常有效的M-矮行星系统的研究，帮助大多数的HADES行星的检测。从可探测性函数中，我们可以计算出早期M矮星周围小质量行星的出现率，或者只考虑11颗已经发表的HADES行星，或者加上在这次分析中发现的5颗新的行星候选者，并将它们与之前对M矮星或太阳型恒星周围行星出现率的估计进行比较：仅考虑已确认的行星，我们发现低质量行星的频率最高（$1$ M $_\oplus < m_p \sin i < 10$ M $_\oplus$），周期为$10$ d $ < P < 100$ d，$f_\text{occ} = 85^{+5}_{-19}\%$，而对于短周期行星（$1$ d $ < P < 10$ d），我们发现频率为$f_\te…
