J/AZh/88/284    Chemical abundance of Hercules moving group  (Pakhomov+, 2011)

Chemical abundance analysis for the atmospheres of red giants in the Hercules moving group. Pakhomov Yu.V., Antipova L.I., Boyarchuk A.A. <Astron. Zh. 88, 284 (2011)> =2011AZh....88..284P =2011ARep...55..256P
ADC_Keywords: Stars, giant; Spectroscopy; Abundances Abstract: The results of a comparative analysis of the kinematics, ages, and elemental abundances for 17 red giants in the Hercules moving group are presented. Model atmospheres are used to determine the parameters of the stellar atmospheres and the abundances of about 20 elements. The masses and ages of the stars are estimated, and the components of their Galactic velocities and the elements of their Galactic orbits are calculated. Our analysis demonstrates that the Hercules stream is a heterogeneous group of objects from the thin and thick disks. File Summary:
