论文摘要

我们报告发现十个短期巨型行星(TOI-2193A B,TOI-2207 B,TOI-2236 B,TOI-2421 B,TOI-2421 B,TOI-2567 B,TOI-2570 B,TOI-2570 B,TOI-3331 B,TOI-3331 B,TOI-3540A B,TOI-3540A B,TOI-3693 B,TOI-3693 B,TOI-3693 B,TOI-3693 B,TOI-4137 B)。所有行星都根据NASA的过境系外行星调查卫星(TESS)观察到的周期性磁通液(TESS)所观察到的所有行星候选。信号被证实来自使用地面时间序列光度法,高角度分辨率成像和高分辨率光谱与TESS随访程序协调的高分辨率光谱术。十个新发现的行星轨道相对明亮的F和G星($ g <12.5 $,〜$ t_ \ mathrm {eff} $在4800和6200 K之间。行星的轨道周期范围为2至10〜天,其质量范围为0.2至2.2木星质量。 TOI-2421 b以土星质量的行星和TOI-2567 B而闻名,因为它是``sup-saturn'',质量分别为$ 0.322 \ pm 0.073 $和$ 0.195 \ pm 0.030 $ 0.030 $ jupiter块。在大多数情况下,我们几乎没有有关轨道偏心率的信息。两个例外是TOI-2207 B,它有8天的时间和可检测到的偏心轨道($ e = 0.17 \ pm0.05 $)和TOI-3693 B,TOI-3693 B,这是一个为期9天的星球,我们可以为其设置上限$ E <0.052 $。这里描述的十个行星是第一个新的行星,这是为了使用苔丝数据来统一和扩展以前的地面过境调查的工作,以创建一个较大且具有统计上有用的热木星样本。

We report the discovery of ten short-period giant planets (TOI-2193A b, TOI-2207 b, TOI-2236 b, TOI-2421 b, TOI-2567 b, TOI-2570 b, TOI-3331 b, TOI-3540A b, TOI-3693 b, TOI-4137 b). All of the planets were identified as planet candidates based on periodic flux dips observed by NASA's Transiting Exoplanet Survey Satellite (TESS). The signals were confirmed to be from transiting planets using ground-based time-series photometry, high angular resolution imaging, and high-resolution spectroscopy coordinated with the TESS Follow-up Observing Program. The ten newly discovered planets orbit relatively bright F and G stars ($G < 12.5$,~$T_\mathrm{eff}$ between 4800 and 6200 K). The planets' orbital periods range from 2 to 10~days, and their masses range from 0.2 to 2.2 Jupiter masses. TOI-2421 b is notable for being a Saturn-mass planet and TOI-2567 b for being a ``sub-Saturn'', with masses of $0.322\pm 0.073$ and $0.195\pm 0.030$ Jupiter masses, respectively. In most cases, we have little information about the orbital eccentricities. Two exceptions are TOI-2207 b, which has an 8-day period and a detectably eccentric orbit ($e = 0.17\pm0.05$), and TOI-3693 b, a 9-day planet for which we can set an upper limit of $e < 0.052$. The ten planets described here are the first new planets resulting from an effort to use TESS data to unify and expand on the work of previous ground-based transit surveys in order to create a large and statistically useful sample of hot Jupiters.
