Abstract:
We present a detailed abundance analysis based on high resolution
spectroscopy for 16 stars in the old open clusters Be 31, Be 32,
Be 39, M 67, NGC 188, and NGC 1193.
Description:
The brighter of the clusters were observed with the echelle
spectrograph on the KPNO 4m on runs in 1996 November/December (NGC 188
and Be 32), 2004 December/2005 January (Be 39, M 67), and 2005
November (additional stars in Be 39, NGC 188). For all these runs we
used the long red camera and the 31.6 line/mm grating and a 1" slit
to give a dispersion of R∼28000. The wavelength coverage in the
1996 run was 5000-8300Å and in the 2004 and 2005 runs was
4800-8100Å.
Fainter stars in clusters NGC 1193 and Be 31 were observed with the
High-Resolution Spectrograph (HRS) on the Hobby-Eberly Telescope (HET)
at McDonald Observatory in a series of queue observations taken in
2004 October through December.
