TL;DR: In this paper, the authors present abundances of Fe, Na, and O for 1409 red giant stars in 15 galactic globular clusters (GCs), derived from the homogeneous analysis of high-resolution FLAMES/GIRAFFE spectra.
Journal ArticleDOI

TL;DR: In this article, the abundances of light elements, α-elements, and Fe-group elements from high-resolution FLAMES spectra are presented for 76 red giant stars in NGC 6715 (M 54), a massive globular cluster (GC) lying in the nucleus of the Sagittarius dwarf galaxy.

TL;DR: In this article, a new observational classification scheme is proposed that takes into account the amplitude as well as the frequency and is applied to categorize 234 stars as δSct, γDor, δ Sct/γDor or γ Dor/Sct hybrids.

TL;DR: In this paper, a new observational classification scheme is proposed that takes into account the amplitude as well as the frequency, and is applied to categorize 234 stars as δ-Sct, δ$ Sct, Δ-Doradus (Dor), Δ-Scuti (Sct), δ-, δ)-Sct/$\gamma$ Dor or δ−Sct hybrids.

M54 + Sagittarius = ω Centauri
Elisa Carretta,Angela Bragaglia,Raffaele Gratton,Sara Lucatello,Sara Lucatello,Michele Bellazzini,Giovanni Catanzaro,Francesco Leone,Yazan Momany,Yazan Momany,Giampaolo Piotto,Valentina D'Orazi +11 more
TL;DR: In this article, the authors derived homogeneous abundances of Fe, O, Na, and α-elements from high-resolution FLAMES spectra for 76 red giant stars in NGC 6715 (M54) and for 25 red giants in the surrounding nucleus of the Sagittarius (Sgr) dwarf galaxy.
