J/PASJ/63/1035  Stellar parameters and abundances of 99 giants  (Wang+, 2011)

Stellar parameters and chemical abundances of G giants. Wang L., Liu Y., Zhao G., Sato B. <Publ. Astron. Soc. Jap., 63, 1035-1046 (2011)> =2011PASJ...63.1035W
ADC_Keywords: Stars, giant ; Stars, G-type ; Abundances ; Space velocities Keywords: stars: abundances - stars: atmospheres - stars: fundamental parameters - stars: late-type Abstract: We present basic stellar parameters of 99 late-type G giants based on high-resolution spectra obtained by the High Dispersion Spectrograph attached to Subaru Telescope. These stars are targets of a Doppler survey program searching for extra-solar planets among evolved stars, with a metallicity of -0.8<[Fe/H]<+0.2. We also derived their abundances of 15 chemical elements, including four α-elements (Mg, Si, Ca, Ti), three odd-Z light elements (Al, K, Sc), four iron peak elements (V, Cr, Fe, Ni), and four neutron-capture elements (Y, Ba, La, Eu). Kinematic properties reveal that most of the program stars belong to the thin disk. Description: Here, we present the first results of these 99 stars, whose spectra were obtained in 2006 July.
