Infrared echelle spectroscopy of Palomar 6 and M71.

LEE J.-W., CARNEY B.W. and BALACHANDRAN S.C.

Abstract (from CDS):

We present high-resolution infrared echelle spectroscopy for the globular clusters Palomar 6 and M71. Our mean heliocentric radial velocity of Pal 6 is +180.6±3.2 km/s and is 20 km/s lower than that found by Minniti in 1995. Contrary to the previous metallicity estimates using low-resolution spectroscopy, our results show that Pal 6 has an intermediate metallicity, with [Fe/H]=-1.0±0.1, and is slightly more metal poor than M71. Reasonable changes in the surface temperature or the microturbulent velocity of the model atmospheres do not affect [Fe/H] at more than ±0.2 dex. In spite of its high metallicity, on the basis of the spectrum of a single cluster member the [Si/Fe] and [Ti/Fe] ratios of Pal 6 appear to be enhanced by 0.4 and 0.5 dex, respectively, suggesting that the Galactic inner halo may have experienced a very rapid chemical enrichment history.
