Lithium and physical properties of planet-host solar-analogue and comparison stars.
图表2 ”有行星“恒星和”无行星“恒星的锂含量以及物理属性
Chromospheric activity indices RHK were taken from the literature 17, 27, 28 while rotational velocities of the comparison sample stars and many planet hosts were measured from CORALIE and HARPS spectra using a cross correlation function 29. Typical 1σ uncertainties for log RHK and vsini (panels (a) and (b), bottom right corner) are 0.1 dex and 0.3 km sec-1 , respectively 17,29. Rotational velocities of several planet-hosts were taken from the literature 29,30. The metallicities were measured 12 with a 1σ precision of 0.05 dex (bottom right corner in panel (c)). In the panel (c )we plot Li abundances versus effective temperature in planet-hosts (red filled circles), and stars of the open clusters M67 (blue triangles) and NGC 6253 (open squares). The data for M67 were taken from the literature 15. Li abundances in NGC 6253 have been derived from VLT/Giraffe spectra using standard methods (Randich et al., in preparation). Typical 1σerror bars (panel (c), bottom right corner) are 0.15 dex and 100 K for log N(Li) and Teff, respectively.
通过应用互相关函数（参考文献29），在CORALIE 和 HARPS 光谱中被测量的”有行星“恒星及对照组样本的旋转速度，色球层活动指数RHK来自于相关文献（参考文献17，27，28）。典型的log RHK 和vsini（图（a）和图（b）的右下角）的1σ不确定性分别为0.1 底什和0.3 km/s（参考文献17，29）。若干”有行星“恒星自转速率来自于相关文献（参考文献29，30）。在0.05底什（c图的右下角）的1σ精度下测量恒星的金属性（参考文献12）。在c(其祥注：困惑，应该是d图啊，难道发表在nature上的论文经过那么多人审核后存在这样的错误)图中，我们所绘制的是锂丰度和”有行星“恒星（实心红圈）的有效温度之间的关系，恒星为M67 （蓝色三角）和 NGC 6253（空心方框）星系中的恒星。M67的数据来自文献15，NGC 6253中锂丰度的数据应用标准法(Randich 等准备).取自于VLT/Giraffe 的光谱。典型的1σ误差线（图c右下角）对应log N(Li) 和 Teff的分别是0.15dex和100k。
终于上传完了，慢慢编辑，慢慢翻译吧。::070821_19.jpg::
LZ辛苦了！好东西，值得收藏！
O(∩_∩)O~，终于全部翻译完了，::070821_02.jpg::。
粗粗看了一下，其祥某些翻译理解有些小错误，我短消息给你吧。
