Abstract

In no other field of astrophysics has the impact of new instrumentation been as substantial as in the domain of exoplanets. Before 1995 our knowledge of exoplanets was mainly based on philosophical and theoretical considerations. The years that followed have been marked, instead, by surprising discoveries made possible by high-precision instruments. Over the past decade, the availability of new techniques has moved the focus of research from the detection to the characterization of exoplanets. Next-generation facilities will produce even more complementary data that will lead to a comprehensive view of exoplanet characteristics and, by comparison with theoretical models, to a better understanding of planet formation.

摘要

在天体物理学的其他领域，新仪器的影响都不如在系外行星领域那么大。在 1995 年之前，我们对系外行星的了解主要基于哲学和理论上的考虑。而在接下来的几年里，高精度仪器的惊人发现改变了这一切。在过去的十年中，新技术的出现使得研究的重点从系外行星的探测转向了它们的特性描述。下一代设施将产生更多的互补数据，从而全面了解系外行星的特性，并通过与理论模型的比较，更好地理解行星形成过程。
