CAPOS: The buge Cluster APOgee Survey. Spectroscopic analysis of Terzan 2

Year: 2024

Type: article

Abstract: We presents the first detailed spectroscopic analysis of the globular cluster Terzan 2 using high-resolution near-infrared spectra obteined through the CAPOS initiative (the APOgee Survey of Clusters in the Galactic Bulge), as a component of the Apache Code for Characterizing High Galactic Evolution Experiment II survey (APOGEE-2). For this we use the Brussels Automatic Code for Characterizing High accUracy Spectra (BACCHUS) code to provide elemental abundances. Our analysis yields a mean metallicity of [Fe/H]= -0.84, with evidence of spread of light element abundance, implying the presence of multiple populations.
