The variable is a single-line spectroscopic binary with an orbital period of 9.8783-days and a large eccentricity of e=0.32. Its systemic velocity (gamma=20.7km/s) and metallicity ([Fe/H]~-1.9) are both consistent with cluster membership. Description: Spectroscopic observations of V32 stars were carried out with the MIKE echelle spectrograph on the Magellan II (Clay) telescope at Las Campanas Observatory. The data were collected during several observing runs between 2005 May and 2007 August.
