论文摘要
从广义上讲，系外行星人口统计调查的主要目标是确定行星的频率和分布，这是可能影响行星形成和进化的尽可能多的物理参数的函数，并尽可能地范围广泛。经验确定的系外行星人口统计提供了一个基础真理，即所有行星形成和进化论都必须繁殖。通过将这些行星分布与行星形成理论的预测进行比较，我们可以开始测试和完善这些理论。在本章中，我们回顾了迄今为止系外行星人口统计数据的主要结果。在这种情况下，我们确定了一组重要的开放问题，这些问题仍有待回答。我们概述了使用各种检测方法来衡量系外行星人口的挑战。最后，我们总结了一些未来的机会，以完善和扩展我们对系外行星人口的理解。
In the broadest sense, the primary goal of exoplanet demographic surveys is to determine the frequency and distribution of planets as a function of as many of the physical parameters that may influence planet formation and evolution as possible, over as broad of a range of these parameters as possible. Empirically-determined exoplanet demographics provide the ground truth that all planet formation and evolution theories must reproduce. By comparing these planet distributions to the predictions of planet formation theories, we can begin to both test and refine these theories. In this chapter, we review the major results on exoplanet demographics to date. In this context, we identify a set of important open questions that remain to be answered. We outline the challenges of measuring the demographics of exoplanets using the variety of detection methods at our disposal. Finally, we summarize some of the future opportunities for refining and expanding our understanding of exoplanet demographics.
