Abstract:
We present abundances for a sample of F, G, and K dwarfs of the
HR 1614 moving group based on high-resolution, high signal-to-noise
ratio spectra from the Anglo-Australian Telescope UCLES instrument.
Our sample includes stars from Feltzing and Holmberg, as well as from
Eggen. Abundances were derived for Na, Mg, Al, Si, Ca, Mn, Fe, Ni, Zr,
Ba, Ce, Nd, and Eu.
Description:
The original data were obtained at the 4m Anglo-Australian Telescope,
using UCLES, in 2003 August. Observations were done at two wavelength
settings at the blue and red. The blue setting was centered at 4130Å
and covers the region from 3800 to 4700Å, while the red setting was
centered at 7040Å, covering the spectral range from 5510 to 10200Å.
The 31.6lines/mm echelle grating was always used. The slit was
opened to a width of 1.2" on the sky, providing a resolving power of
48000.
