标题： The TESS Grand Unified Hot Jupiter Survey. III. Thirty More Giant Planets

摘要： 我们介绍了发现的30颗凌日巨行星，这些行星最初是通过NASA的凌日系外行星勘测卫星（TESS）任务的数据检测到的。 这些新发现的行星围绕相对明亮（$G \leq 12.5$）的FGK型恒星运行，轨道周期在1.6到8.2天之间，半径在0.9到1.7倍木星半径之间。 我们对每个天体进行了后续的地面光度测量、高角分辨率成像、高分辨率光谱和径向速度监测，以确认它们是行星并确定其质量和其它系统参数。 这些行星的质量跨度超过一个数量级（$0.17\,M_J < M_p < 3.3\,M_J$）。 对于两颗行星TOI-3593 b和TOI-4961 b，我们分别测得了显著非零的偏心率$0.11^{+0.05}_{-0.03}$和$0.18^{+0.04}_{-0.05}$，而对于其他行星，数据通常提供了一个0.15的偏心率1-$\sigma$上限。 这些发现代表了向建立一个完整的、亮度限制的围绕FGK星的凌日热木星样本迈出了重要一步。 显示英文摘要

摘要： We present the discovery of 30 transiting giant planets that were initially detected using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission. These new planets orbit relatively bright ($G \leq 12.5$) FGK host stars with orbital periods between 1.6 and 8.2 days, and have radii between 0.9 and 1.7 Jupiter radii. We performed follow-up ground-based photometry, high angular-resolution imaging, high-resolution spectroscopy and radial velocity monitoring for each of these objects to confirm that they are planets and determine their masses and other system parameters. The planets' masses span more than an order of magnitude ($0.17\,M_J < M_p < 3.3\,M_J$). For two planets, TOI-3593 b and TOI-4961 b, we measured significant non-zero eccentricities of $0.11^{+0.05}_{-0.03}$ and $0.18^{+0.04}_{-0.05}$ respectively, while for the other planets, the data typically provide a 1-$\sigma$ upper bound of 0.15 on the eccentricity. These discoveries represent a major step toward assembling a complete, magnitude-limited sample of transiting hot Jupiters around FGK stars.
