太阳系外行星的发现(莱瑟姆等人,1989;沃尔兹赞等人,1992;马约尔和奎洛兹,1995)可以说是过去二十年来天文观测中最令人兴奋的发展之一。在撰写本文时,已知有400多颗行星围绕太阳以外的恒星运行。这些行星中的大多数是使用所谓的“多普勒摆动”方法发现的:由于星星围绕恒星-行星质心的运动,测量恒星吸收线的微妙多普勒频移。
The discovery of extrasolar planets (Latham et al. 1989; Wolszczan et al. 1992; Mayor and Queloz 1995) is arguably one of the most exciting developments in astronomical observations in the past two decades. At the time of this writing over 400 planets were known to orbit around stars other than the Sun. Majority of these planets have been discovered using the so-called “Doppler wobble” method: the measurement of the subtle Doppler shifts of the stellar absorption lines due to the motion of the star about the star-planet barycenter.
