双星系统引起的恒星摆动：它真的会被误认为是太阳系外行星吗？
Stellar wobble caused by a binary system: Can it really be mistaken as an extra-solar planet?
摘要：
探测太阳系外行星的传统方法依赖于测量一个小的恒星摆动，这被认为是由一颗行星绕恒星运行引起的。最近，有人提出类似的恒星摆动可能是由近距离双星系统引起的（Schneider和Cabrera，2006）。在这里，我们表明，虽然一个紧密的双系统的影响，乍一看可能被误认为是一个行星的伴侣恒星，更仔细的分析观测数据应该让我们区分这两种影响。
英文摘要：
The traditional method for detecting extra-solar planets relies on measuring a small stellar wobble which is assumed to be caused by a planet orbiting the star. Recently, it was suggested that a similar stellar wobble could be caused by a close binary system (Schneider and Cabrera, 2006). Here we show that, although the effect of a close binary system can at first sight be mistaken as a planetary companion to the star, more careful analysis of the observational data should allow us to distinguish between the two effects.
