Chemical abundances in the globular clusters NGC 5024 and NGC 5466 from optical ★ and infrared spectroscopy

Detailed chemical abundances for five stars in two Galactic globular clusters, NGC 5466 and NGC 5024, are presented from high-resolution optical (from the Hobby-Eberley Telescope) and infrared spectra (from the SDSS-III APOGEE survey). We find [Fe/H] = −1.97 ± 0.13 dex for NGC 5466, and [Fe/H] = −2....
