Journal ArticleDOI
Light element abundances in the young open clusters NGC 3293, NGC 4755 and NGC 6231: Tracers of stellar evolution
Gautier Mathys,Sergei M. Andrievsky,Sergei M. Andrievsky,Beatriz Barbuy,Katia Cunha,S. A. Korotin,S. A. Korotin +6 more
TL;DR: The abundances of He (LTE), C, N, and O (NLTE) were derived for 21 B stars in three young open clusters in this article, and the mean helium abundance for each cluster is close to the standard value, (He/H) 11:0.
Journal ArticleDOI

TL;DR: In this article, the abundances from HF lines in infrared K-band spectra (at 2.3 microns) of cool giants, observed with the IGRINS and Phoenix high-resolution spectrographs, were determined.

TL;DR: In this article, the authors present stellar age distributions of the Milky Way bulge region using ages for 6,000 high-luminosity stars, and identify a non-negligible fraction of younger stars at metallicities of +0.2 < [Fe/H] < + 0.4.
