摘要: 太阳系外行星的探测与研究是目前国际上的前沿热门领域。近年来,随着一些关键探测技术的突破,以及空间望远镜的使用,相继发现了900多颗太阳系外行星。这些太阳系外行星系统的发现,对现有的行星形成和演化模型提出了新的挑战。首先介绍了两种目前比较公认的行星形成机制,并提出了系外行星探测的一些热点问题,指出未来太阳系外行星系统的探测计划重要目标之一是发现宜居行星。最后,简单介绍了将要实施或正在实施的一些国际国内太阳系外行星的探测计划。

Abstract: The detection of exoplanets becomes a hot research. With some breakthrough in detection and the advance of the space exploring, more than 900 exoplanets have recently been discovered with multiple techniques. Many characteristics quite different with the solar system are found in exoplanets and their orbital configurations. These new phenomena are testing out the traditional planetary formation model. The gravitational instability model and the core accretion model of planetary formation are briefly introduced. At the end of the paper, author introduced a few future exoplanet hunting program of international and China.
