论文摘要
太空任务苔丝和柏拉图计划将已经发现的4000个系外行星的数量增加一倍，并将测量天空中最明亮的恒星周围数千个系外行星的大小，从而允许地面径向速度光谱频谱随访，以确定检测到的星球的轨道和质量。我们正在开发的新设施Marvel（Raskin等人。本次会议）将对TESS和PLATO的大量系外行星检测进行基于地面的随访，这只能由当前的设施来实现所需的径向速度准确性1 m/s或更少。本文根据预测的柏拉图过境检测产量模拟了漫威观察策略和绩效分析。由此产生的观察场景基线将有助于仪器设计选择，并证明奇迹作为苔丝和柏拉图科学促进设施的有效性。
The space missions TESS and PLATO plan to double the number of 4000 exoplanets already discovered and will measure the size of thousands of exoplanets around the brightest stars in the sky, allowing ground-based radial velocity spectroscopy follow-up to determine the orbit and mass of the detected planets. The new facility we are developing, MARVEL (Raskin et al. this conference), will enable the ground-based follow-up of large numbers of exoplanet detections, expected from TESS and PLATO, which cannot be carried out only by the current facilities that achieve the necessary radial velocity accuracy of 1 m/s or less. This paper presents the MARVEL observation strategy and performance analysis based on predicted PLATO transit detection yield simulations. The resulting observation scenario baseline will help in the instrument design choices and demonstrate the effectiveness of MARVEL as a TESS and PLATO science enabling facility.
