摘要:

在这一章的书“行星在双星”,我们总结了我们最近的工作统计性质的行星在双星和差异方面的行星轨道单星。然后,我们提出了径向速度行星搜索中等宽的双星相似的组件(双胞胎)正在TNG使用高分辨率摄谱仪SARG。本文讨论了径向速度监测的样品选择、观测和分析过程以及初步结果。我们还讨论了SARG调查的第二个主要科学目标,寻找由中央恒星摄入行星物质引起的丰度异常,考虑到两个样本的双胞胎和具有相似成分的双星中的行星宿主。最后,我们提出了一些初步的结论,在双星系统中的行星的频率。

英文摘要:

In this chapter of the book "Planets in binaries" we summarize our recent work on the statistical properties of planets in binaries and the differences with respect to planets orbiting single stars. We then present the radial velocity planet search on moderately wide binaries with similar components (twins) ongoing at TNG using the high resolution spectrograph SARG. We discuss the sample selection, the observing and analysis procedures, and the preliminary results of the radial velocity monitoring. We also discuss the second major science goal of the SARG survey, the search for abundance anomalies caused by the ingestion of planetary material by the central star, considering the two samples of twins and the planet hosts in binaries with similar components. Finally, we present some preliminary conclusions on the frequency of planets in binary systems.
