Spectroscopic Study of Blue Straggler Stars in the Globular Cluster NGC 3201

We conducted a spectroscopic study of 39 blue straggler stars in the globular cluster NGC 3201. The spectra of these stars have been previously reported. We determined the radial velocity, atmospheric parameters (T𝑒𝑓𝑓 , log 𝑔), Mg abundance, and metallicity ([Fe/H]) for all sources in the sample. The mean radial velocity and [Fe/H] were determined to be 498.0±5.3 km/s and -1.42±0.27, respectively. The derived [Fe/H] is consistent, within uncertainties, with the cluster’s [Fe/H] of -1.59 dex. The mean [Mg/Fe] for the sample was estimated to be 0.36±0.73. Importantly, this study is the first to estimate [Mg/Fe] for blue straggler stars in the cluster NGC 3201.
