| 英文摘要 | We present stellar atmospheric parameters, and kinematic parameters for a part of Xinglong Planet Search Program sample 58 late G-type giants, obtained at Okayama Astrophysical Observatory. Additionally, we determined the chemical abundances, especially for the elements C, O, and Na. The metallicity distribution of our sample ranges covered from 0.6 to 0.2 in [Fe/H], which supports the previous results, suggesting a lack of super metal-rich giants with [Fe/H] > +0.2. The abundance of C is depleted by 0.13 dex, and [Na/Fe] shows an overabundance of 0.1 dex compared to a dwarf with the same spectral type, while the 0 abundance was not altered after the first dredge up. These results are consistent with theoretical predictions of stellar evolution. The behaviors of Si, Ca, Ti, Cr, Ni, Mn, Sc II, Y II, and Ce II in our giants follow the same trends as in dwarfs. |
