来自透射光谱学和其他行星-恒星组合光观测的系外行星大气测量

Exoplanet Atmosphere Measurements from Transmission Spectroscopy and other Planet-Star Combined Light Observations

Laura Kreidberg

摘要:

即使我们无法从空间上分辨行星与其宿主恒星,也有可能了解大量关于系外行星大气的信息。在本章中,我们将概述用于描述凌日系外行星的基本技术-透射光谱学,发射和反射光谱学,以及全轨道相位曲线观测。我们讨论实际的考虑,包括当前和未来的观测设施和测量精确光谱的最佳实践。我们还强调了关于系外行星的化学,气候和云特性的主要观测结果。

英文摘要:

It is possible to learn a great deal about exoplanet atmospheres even when we cannot spatially resolve the planets from their host stars. In this chapter, we overview the basic techniques used to characterize transiting exoplanets - transmission spectroscopy, emission and reflection spectroscopy, and full-orbit phase curve observations. We discuss practical considerations, including current and future observing facilities and best practices for measuring precise spectra. We also highlight major observational results on the chemistry, climate, and cloud properties of exoplanets.
