Near-IR spectroscopy of OH/IR stars in the Galactic centre.

Abstract (from CDS):

Based on the expansion velocities of their circumstellar shells, Galactic centre (GC) OH/IR stars can be divided into two groups that are kinematically different and therefore believed to have evolved from different stellar populations. We studied the metallicity distribution of the OH/IR stars population in the GC on the basis of a theoretical relation between EW(Na), EW(Ca), and EW(CO) and the metallicity. For 70 OH/IR stars in the GC, we obtained near-IR spectra. The equivalent line-widths of NaI, CaI, 12CO(2,0), and the curvature of the spectrum around 1.6µm due to water absorption were determined. The near-IR spectrum of OH/IR stars is influenced by several physical processes. OH/IR stars are variable stars suffering high mass-loss rates. The dust that is formed around the stars strongly influences the near-IR spectra and reduces the equivalent line-widths of NaI and CaI. A similar effect is caused by the water content in the outer atmosphere of the OH/IR star. Because of these effects, it is not possible to determine the metallicities of these stars with our low-resolution near-infrared spectroscopy.
