| 英文摘要 | High resolution (R similar to 40,000) and high signal-to-noise ratio (>150) spectra of two solar twins, HD146233 and HD195034, are obtained with the Coude Echelle Spectrograph at the 2.16 m telescope of the National Astronomical Observatories of Chinese Academy of Sciences (Xinglong, China). Based on the detailed spectrum match, comparisons of chemical composition and chromospheric activity, HD146233 and HD195034 are confirmed that they are similar to the Sun except for lithium abundance, which is higher than the solar value. Moreover, among nine solar twin candidates (including HD146233 and HD195034) found in the previous works, we have picked out six good solar twin candidates based on newly-derived homogenous parameters, and collected their colors in the Johnson/Cousins, Tycho, 2MASS and StrOmgren system from the literature. The average color are (B-V)(circle dot)=0.644 mag, (V-I(c))(circle dot)=0.707 mag, (B(T)-V(T))(circle dot)=0.725 mag, (J-H)(circle dot)=0.288 mag, (H-K)(circle dot)=0.066 mag, (v-y)(circle dot)=1.028 mag, (v-b)(circle dot)=0.619 mag, (u-v)(circle dot)=0.954 mag and (b-y)(circle dot)=0.409 mag, which represent the solar colors with higher precision than previous works. |
