We present the discovery and characterization of five hot and warm Jupiters—TOI-628 b (TIC 281408474; HD 288842), TOI-640 b (TIC 147977348), TOI-1333 b (TIC 395171208, BD+47 3521A), TOI-1478 b (TIC 409794137), and TOI-1601 b (TIC 139375960)—based on data from NASA’s Transiting Exoplanet Survey Satellite (TESS). The five planets were identified from the full-frame images and were confirmed through a series of photometric and spectroscopic follow-up observations by the TESS Follow-up Observing Program Working Group. The planets are all Jovian size (R _P = 1.01–1.77 R _J) and have masses that range from 0.85 to 6.33 M _J. The host stars of these systems have F and G spectral types (5595 ≤ T _eff ≤ 6460 K) and are all relatively bright (9.5 < V < 10.8, 8.2 < K < 9.3), making them well suited for future detailed characterization efforts. Three of the systems in our sample (TOI-640 b, TOI-1333 b, and TOI-1601 b) orbit subgiant host stars ( $\mathrm{log}$ g < 4.1). TOI-640 b is one of only three known hot Jupiters to have a highly inflated radius (R _P > 1.7 R _J, possibly a result of its host star’s evolution) and resides on an orbit with a period longer than 5 days. TOI-628 b is the most massive, hot Jupiter discovered to date by TESS with a measured mass of ${6.31}_{-0.30}^{+0.28}$ M _J and a statistically significant, nonzero orbital eccentricity of e = ${0.074}_{-0.022}^{+0.021}$ . This planet would not have had enough time to circularize through tidal forces from our analysis, suggesting that it might be remnant eccentricity from its migration. The longest-period planet in this sample, TOI-1478 b (P = 10.18 days), is a warm Jupiter in a circular orbit around a near-solar analog. NASA’s TESS mission is continuing to increase the sample of well-characterized hot and warm Jupiters, complementing its primary mission goals.

苔丝从全帧图像中提供了五颗新的热巨行星围绕明亮的恒星运行

我们介绍了五颗热木星和暖木星的发现和表征——TOI-628 b (TIC 281408474; HD 288842)、TOI-640 b (TIC 147977348)、TOI-1333 b (TIC 395171208, BD+47-A), 352 1478 b (TIC 409794137) 和 TOI-1601 b (TIC 139375960)——基于来自美国宇航局过境系外行星勘测卫星 (TESS) 的数据。这五颗行星是从全帧图像中识别出来的，并通过 TESS 后续观测计划工作组的一系列光度和光谱后续观测得到确认。这些行星都是木星大小（R _P = 1.01–1.77 R _J），质量范围从 0.85 到 6.33 M _J。这些系统的主星具有 F 和 G 光谱类型（5595 ≤ T _eff≤ 6460 K）并且都相对明亮（9.5 < V < 10.8，8.2 < K < 9.3），使它们非常适合未来的详细表征工作。我们样本中的三个系统（TOI-640 b、TOI-1333 b 和 TOI-1601 b）围绕次巨星宿主恒星运行（ $\mathrm{log}$ g < 4.1）。TOI-640 b 是仅有的三颗已知半径高度膨胀的热木星之一（R _P > 1.7 R _J，可能是其主星演化的结果）并且驻留在轨道上的周期超过 5 天。TOI-628 b 是迄今为止由 TESS 发现的质量最大、最热的木星，其测量质量为 ${6.31}_{-0.30}^{+0.28}$ M _J，具有统计显着性的非零轨道偏心率e = ${0.074}_{-0.022}^{+0.021}$ . 根据我们的分析，这颗行星没有足够的时间通过潮汐力进行循环，这表明它可能是迁移后的残余偏心率。该样本中周期最长的行星 TOI-1478 b（P = 10.18 天）是一颗温暖的木星，它位于一个环绕近太阳模拟的圆形轨道上。NASA 的 TESS 任务正在继续增加特征鲜明的热木星和温暖木星的样本，以补充其主要任务目标。
