Light Element Abundance Patterns in the Orion Association: I) HST Observations of Boron in G-dwarfs
TL;DR: In this article, the boron abundances for two young solar-type members of the Orion association, BD -6 1250 and HD 294297, were derived from HST STIS spectra of the B I transition at 2496.
Journal ArticleDOI

TL;DR: In this paper, the authors used SDSS/APOGEE DR16 of a sample of 128 open clusters, 71 of which they designated to be "high quality" based on the appearance of their color-magnitude diagram.
Journal ArticleDOI
Lithium Inventory of 2 Solar Mass Red Clump Stars in Open Clusters: A Test of the Helium Flash Mechanism
TL;DR: In this paper, the authors measured abundances in 38 Li-rich red clump stars and 6 red giant branch (RGB) stars in four open clusters selected to have RC masses near 2 solar mass.
Journal ArticleDOI
MANGANESE ABUNDANCES IN THE GLOBULAR CLUSTER ω CENTAURI
TL;DR: In this paper, manganese abundances in 10 red giant members of the globular cluster? Centauri were studied and it was shown that low-metallicity supernovae of either Type?II or Type Ia dominated the enrichment of the more metal-rich stars in? Cen.

TL;DR: In this paper, high-resolution spectra obtained in the near-infrared region around 2.3 μm with the Phoenix spectrograph on the 8.1 m Gemini South Telescope, the IGRINS spectrograp on the McDonald Observatory 2.7 m Telescope, and the CRIRES spectrogram on the ESO 8.2 m Very Large Telescope were analyzed.
