Abstract:
We present an analysis of high-dispersion echelle spectra of three
giant stars in the 10Gyr open cluster Berkeley 17 obtained with the
KPNO 4m Telescope. Abundances were determined relative to the bright,
somewhat metal-poor disk giant Arcturus.
Description:
Observations of the four target stars in the field of Be 17 were
obtained with the echelle spectrograph on the 4m telescope at KPNO on
the nights of 1996 November 28 through December 2 (UT).
