The Aquarius comoving group is not a disrupted classical globular cluster
We present a detailed analysis of high-resolution, high signal-to-noise ratio spectra for five Aquarius stream stars observed with the Magellan Inamori Kyocera Echelle spectrograph on theMagellan Clay telescope. Our sample represents one-third of the 15 known members in the stream.We find the stream is not monometallic: the metallicity ranges from [Fe/H]=-0.63 to -1.58. No anticorrelation in Na-O abundances is present, and we find a strong positive Mg-Al relationship, similar to that observed...[Show more]
