Abstract:
We present model atmosphere analyses of high resolution Keck and VLT
optical spectra for three evolved stars in globular clusters, viz.
ZNG-1 in M10, ZNG-1 in M15 and ZNG-1 in NGC6712. The derived
atmospheric parameters and chemical compositions confirm the programme
stars to be in the post-Asymptotic Giant Branch (post-AGB)
evolutionary phase.
Description:
NGC 6712 ZNG-1 was observed on the 4 July 2000 with the 10m Keck I
telescope. M10 ZNG-1 and M15 ZNG-1 were observed during the period
01-03 July 2001 with the 8m VLT KUEYEN telescope.
The table presents absorption line equivalent widths (in mÅ) for
the 3 globular cluster stars: M10 ZNG-1, M15 ZNG-1 and NGC 6712
ZNG-1. The first column lists the species, the second the rest
wavelength for the line, and columns 3-5 list the equivalent widths
(where measurable). Where 2 wavelengths are given for a single
species, the measured line equivalent width is a blend.
