Investigating Phosphorus Abundances in a Sample of APOGEE-2 Bulge Globular Clusters
Beatriz Barbuy, José G. Fernández-Trincado, Morgan S. Camargo +9
Phosphorus enhanced (P-rich; [P/Fe] > 0.8) giants have been found among mildly metal-poor fiels stars, but in only one star in a globular cluster (GC), M4 (NGC 6121). Also, in a sa…
Atmospheric parameters and chemical abundances of young stars with APOGEE. I. Orion star-forming region
Ricardo López-Valdivia, Lucía Adame, Carlos G. Román-Zúñiga +19
We derive atmospheric parameters and chemical abundances in young G-, K-, and M-type stars (temperatures between 6500 and 3100 K) using infrared APOGEE-2 spectra. Atmospheric param…
The blue straggler population of the open clusters Trumpler 5, Trumpler 20, and NGC 2477
M. J Rain, G. Carraro, J. Ahumada +3
We present a study, based on Gaia DR2, of the population of blue straggler stars (BSS) in the open clusters Trumpler 5, Trumpler 20, and NGC 2477. All candidates were selected acco…
The vertical Na-O relation in the bulge globular cluster NGC 6553
C. Muñoz, S. Villanova, D. Geisler +7
In this article, we present a detailed chemical analysis of seven red giant members of NGC 6553 using high-resolution spectroscopy from VLT FLAMES. We obtained the stellar paramete…
A study of the blue straggler population of the old open cluster Collinder 261
M. J. Rain, G. Carraro, J. A. Ahumada +4
Blue Stragglers are stars located in an unexpected region of the color-magnitude diagram of a stellar population, as they appear bluer and more luminous than the stars in the turno…
The peculiar Na-O anticorrelation of the bulge globular cluster NGC 6440
C. Muñoz, S. Villanova, D. Geisler +4
Context. Galactic Globular Clusters (GCs) are essential tools to understand the earliest epoch of the Milky Way, since they are among the oldest objects in the Universe and can be…
