空间系外行星探测与研究进展

Progress on Exoplanet Detection and Research in Space

系外行星学科是近30年来迅速发展起来的一门新兴学科.其主要研究内容和目标包括,通过发展各种探测技术探测太阳系外行星,分析行星轨道、成分、大气性质,评估行星的宜居性,统计行星的分布规律,从理论和观测上揭示行星系统的形成和动力学演化机制.系外行星的研究对于回答宇宙中是否存在其他生命以及人类在宇宙中的地位和意义等问题具有重要意义.随着21世纪空间探测技术的发展,系外行星的研究进入了崭新及快速的发展阶段.本文分析了系外行星研究领域的发展态势,凝练中国在系外行星未来空间探测发展的重点领域,优化学科布局,以推进系外行星研究的快速稳步发展.

The subject of exoplanets has been a rapidly developing discipline in the past thirty years.Its main research content and objectives include:detecting exoplanets through the development of various detection techniques,analyzing planetary orbits,composition and atmospheric properties,evaluating the habitability of planets,calculating the distribution patterns of planets,and revealing the formation and dynamical evolution of planetary systems from both theoretical and observational perspectives.The study of exoplanets is of great significance in answering questions about the existence of other life forms in the universe and the status of humans in the universe.With the development of space exploration technology in the 21st century,the study of exoplanets has entered a new era.This article summarizes the development trend in the field of exoplanets,condenses China’s key areas for future space exploration of exoplanets,optimizes the discipline layout,and promotes high-quality development of exoplanet research.
