Abstract:
We present analysis of high-resolution spectra of a sample of stars in
the globular cluster M5 (NGC 5904). The sample includes stars from the
red giant branch (RGB; seven stars), the red horizontal branch (two
stars), and the asymptotic giant branch (AGB; eight stars), with
effective temperatures ranging from 4000K to 6100K. Spectra were
obtained with the HIRES spectrometer on the Keck I telescope, with a
wavelength coverage from 3700Å to 7950Å for the HB and AGB
sample, and 5300Å to 7600Å for the majority of the RGB sample.
Description:
Our spectra were obtained using the HIRES spectrograph on the Keck 1
telescope. On 2007 June 5-7, we observed the AGB, HB, and part of our
RGB sample with the recently upgraded detector focal plane, a setup
that provided near continuous wavelength coverage between 3700 and
7950Å. The remainder of the RGB sample is from an earlier run on
2000 June 6 with the original HIRES CCD, and therefore covers a more
limited wavelength range of 5300-7600Å.
