论文摘要

我们介绍了遥远的巨人调查,这是一项为期三年的径向速度(RV),以测量P(DG | CS),在托管一个托管近距离的小行星(CS; R_P <10 r_e)的系统中,远处巨型行星(DG; M_P 〜0.3-0.3-13-13 m_j,p> 1年)的条件发生。在过去的两年中,我们监视了47个类似阳光的恒星,这些星星托有苔丝检测到的小型过境行星。我们介绍了用于组装样本的选择标准,并报告发现两个遥远的巨型行星TOI-1669 B和TOI-1694 c。对于TOI-1669 B,我们发现MSIN I = 0.573 +/- 0.074 M_J,P = 502 +/- 16天,而E <0.27,而对于TOI-1694 C,MSIN I = 1.05 +/- 0.05 M_J,P = 389.2 +/- 3.9天,E = 3.9天,E = 0.18 +/0.18 +/0.05。我们还通过测量M = 26.1 +/- 2.2 m_e来证实3.8天的Transing Planet TOI-1694 B。我们还通过测量M = 26.1 +/- 2.2 m_e来证实3.8天的Transing Planet TOI-1694 B。在遥远的巨人调查结束时,我们将将TOI-1669 B和TOI-1694 C纳入P(DG | CS)的计算,这是一种重要的统计量,用于了解外部巨人与小型内部伴侣之间的关系。

We present the Distant Giants Survey, a three-year radial velocity (RV) campaign to measure P(DG|CS), the conditional occurrence of distant giant planets (DG; M_p ~ 0.3 - 13 M_J, P > 1 year) in systems hosting a close-in small planet (CS; R_p < 10 R_E). For the past two years, we have monitored 47 Sun-like stars hosting small transiting planets detected by TESS. We present the selection criteria used to assemble our sample and report the discovery of two distant giant planets, TOI-1669 b and TOI-1694 c. For TOI-1669 b we find that Msin i = 0.573 +/- 0.074 M_J, P = 502 +/- 16 days, and e < 0.27, while for TOI-1694 c, Msin i = 1.05 +/- 0.05 M_J, P = 389.2 +/- 3.9 days, and e = 0.18 +/- 0.05. We also confirmed the 3.8-day transiting planet TOI-1694 b by measuring a true mass of M = 26.1 +/- 2.2 M_E. We also confirmed the 3.8-day transiting planet TOI-1694 b by measuring a true mass of M = 26.1 +/- 2.2 M_E. At the end of the Distant Giants Survey, we will incorporate TOI-1669 b and TOI-1694 c into our calculation of P(DG|CS), a crucial statistic for understanding the relationship between outer giants and small inner companions.
