标题： Validation of TESS Planet Candidates with Multi-Color Transit Photometry and TRICERATOPS+

摘要： 我们介绍了TRICERATOPS的升级版本，这是一个用于计算由凌日系外行星勘测卫星（TESS）识别的行星候选者的假阳性概率的软件包。 此增强框架现在结合了不同波段的地基光曲线，这些光曲线通常作为候选者验证过程的一部分获得。 我们将这个升级后的框架应用于探索14个TESS行星候选者的行星性质，主要结合使用帕洛玛天文台200英寸海尔望远镜获取的J波段光曲线与来自拉斯坎布雷斯天文台全球望远镜（LCOGT）、弗雷德·劳伦斯·惠普尔天文台（FLWO）和特内里费天文台的补充档案观测数据，以及现有的TESS数据和高分辨率成像的对比曲线。 通过这种分析，我们统计验证了六个新的行星，位于五个系统中：TOI-1346 b、TOI-1346 c、TOI-2719 b、TOI-4155 b、TOI-6000 b和TOI-6324 b。 对于这些系统，我们提供了基于TESS和地基观测的恒星和行星性质的更新估计。 这些新系统包含半径在0.9-6 Re 之间、轨道周期在0.3-5.5天之间的行星。 最后，我们使用升级后的TRICERATOPS版本量化多波长凌日测光和高分辨率成像在系外行星候选者验证中的相对重要性，并讨论哪些类型的候选者通常最受益于地基多色凌日观测。 显示英文摘要

摘要： We present an upgraded version of TRICERATOPS, a software package designed to calculate false positive probabilities for planet candidates identified by the Transiting Exoplanet Survey Satellite (TESS). This enhanced framework now incorporates ground-based light curves in separate bandpasses, which are routinely obtained as part of the candidate vetting process. We apply this upgraded framework to explore the planetary nature of 14 TESS planet candidates, combining primarily J band light curves acquired with the 200-inch Hale Telescope at Palomar Observatory with complementary archival observations from the Las Cumbres Observatory Global Telescope (LCOGT), the Fred Lawrence Whipple Observatory (FLWO), and the Teide Observatory, along with existing TESS data and contrast curves from high-resolution imaging. As a result of this analysis we statistically validate (False Positive Probability < 1.5% and Nearby False Positive Probability < 0.1%) six new planets in five systems: TOI-1346 b, TOI-1346 c, TOI-2719 b, TOI-4155 b, TOI-6000 b, and TOI-6324 b. For these systems, we provide updated estimates of their stellar and planetary properties derived from the TESS and ground-based observations. These new systems contain planets with radii between 0.9-6 Re and orbital periods between 0.3-5.5 days. Finally, we use our upgraded version of TRICERATOPS to quantify the relative importance of multi-wavelength transit photometry and high-resolution imaging for exoplanet candidate validation, and discuss which kinds of candidates typically benefit the most from ground-based multi-color transit observations.
