绘制出系外行星过程的时间演化图

Mapping out the time-evolution of exoplanet processes

Jessie L. Christiansen, Charles Beichman, David R. Ciardi, Daniel Huber, Mark S. Marley

摘要:

有许多相互竞争的理论和模型描述系外行星系统的形成,迁移和演化。随着我们可以描述系外行星及其宿主恒星的精度以及我们可以进行这种表征的系统数量的增加,我们开始看到验证这些理论的途径。在这份白皮书中,我们确定了在不久的将来可以获得的预测,可观察的相关性,特别是系外行星种群,半径,轨道和大气层与宿主恒星年龄的趋势。通过编制一个具有统计意义的样本,这些样本具有精确测量的年龄,我们应该能够开始确定控制系外行星系统时间演化的主导过程。

英文摘要:

There are many competing theories and models describing the formation, migration and evolution of exoplanet systems. As both the precision with which we can characterize exoplanets and their host stars, and the number of systems for which we can make such a characterization increase, we begin to see pathways forward for validating these theories. In this white paper we identify predicted, observable correlations that are accessible in the near future, particularly trends in exoplanet populations, radii, orbits and atmospheres with host star age. By compiling a statistically significant sample of well-characterized exoplanets with precisely measured ages, we should be able to begin identifying the dominant processes governing the time-evolution of exoplanet systems.
