M31 integrated light abundances
Listed in IVOA Registry (Virtual Observatory)
We report the first detailed chemical abundances for five globular clusters (GCs) in M31 from high-resolution (R~25000) spectroscopy of their integrated light (IL).
Description
These GCs are the first in a larger set of clusters observed as part of an ongoing project to study the formation history of M31 and its GC population. The data presented here were obtained with the HIRES echelle spectrograph on the Keck I telescope and are analyzed using a new IL spectra analysis method that we have developed.
In these clusters, we measure abundances for Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Y, and Ba, ages >=10Gyr, and a range in [Fe/H] of -0.9 to -2.2. As is typical of Milky Way GCs, we find these M31 GCs to be enhanced in the {alpha}-elements Ca, Si, and Ti relative to Fe.
