Abstract:
We present Mg isotope ratios in four red giants of the globular
cluster M13 and one red giant of the globular cluster M71 based on
high-resolution, high signal-to-noise ratio spectra obtained with HDS
on the Subaru Telescope.
Description:
Observations of the four M13 red giants and the M71 red giant were
obtained with the Subaru Telescope using the High Dispersion
Spectrograph on 2004 June 1.
