AI 中文摘要
系外行星科学的主要目标是表征系外类地行星以及导致不同气候结果的条件。金星区域（VZ）为识别可能经历过类似金星的失控温室过程的行星提供了一个框架，这类行星的统计特性直接关系到行星宜居性模型。在此，我们对欧洲航天局普朗克卫星（PLATO，行星凌星和恒星振荡）任务中金星区域类地行星的预期产量进行了定量估计。我们将预测的普朗克卫星对地球大小（0.8 - 1.25R⊕）和超级地球（1.25 - 2.0R⊕）行星的产量与从开普勒数据得出的金星区域类地行星的经验发生率相结合。在保守假设下，我们估计普朗克卫星在名义上的4年任务期间将探测到约170 - 280颗金星区域类地行星（0.8 - 2.0R⊕），包括约40 - 80颗地球大小（0.8 - 1.25R⊕）的行星。对于明亮的P1样本（V≤11），我们估计将探测到约50 - 85颗类地行星和约13 - 22颗地球大小的金星区域行星，从而能够利用詹姆斯·韦布空间望远镜和未来设施对最有利的目标进行径向速度质量测定和大气特征描述。我们讨论了这一产量对于地球 - 金星差异比较研究的意义、与前往金星的DAVINCI、VERITAS和EnVision任务的协同作用，以及普朗克卫星在推进我们对失控温室边界理解方面的作用。
英文摘要
The characterization of terrestrial exoplanets and the conditions that lead to divergent climate outcomes is a primary goal of exoplanetary science. The Venus Zone (VZ) provides a framework for identifying planets that may have experienced runaway greenhouse processes similar to Venus, and the statistical properties of such planets bear directly on models of planetary habitability. Here we present a quantitative estimate of the expected yield of VZ terrestrial planets from ESA's PLATO (PLAnetary Transits and Oscillations of stars) mission. We combine the predicted PLATO planet yield for Earth-size ($0.8$--$1.25~R_\oplus$) and super-Earth ($1.25$--$2.0~R_\oplus$) planets with empirical occurrence rates for VZ terrestrial planets derived from Kepler data. Under conservative assumptions, we estimate that PLATO will detect $\sim$170--280 VZ terrestrial planets ($0.8$--$2.0~R_\oplus$), including $\sim$40--80 Earth-size ($0.8$--$1.25~R_\oplus$) planets, during a nominal 4-year mission. For the bright P1 sample ($V \leq 11$), we estimate $\sim$50--85 terrestrial and $\sim$13--22 Earth-size VZ detections, enabling radial velocity mass determination and atmospheric characterization of the most favorable targets with JWST and future facilities. We discuss the implications of this yield for comparative studies of Earth-Venus divergence, synergies with the DAVINCI, VERITAS, and EnVision missions to Venus, and the role of PLATO in advancing our understanding of the runaway greenhouse boundary.
