Tracing Red Giant Members of the Globular Cluster Palomar 5 with APOGEE and Gaia
Allyson A. Sheffield, Sarah Pearson, Lenin F. Nolasco +5
The globular cluster Palomar 5 (Pal 5) is in the process of being tidally shredded as it orbits the Milky Way. Its core is currently at a heliocentric distance of ~21 kpc, near apo…
Open cluster members in APOGEE DR17 I. Dynamics and star members
R. Guerço, D. Souto, J. G. Fernández-Trincado +7
Context. Open clusters (OCs) are groups of stars formed from the same cloud of gas and cosmic dust. They play an important role in studies of star formation and evolution and our u…
Fluorine production in He-burning regions of massive stars during cosmic history
Sophie Tsiatsiou, Georges Meynet, Eoin Farrell +11
The origin of fluorine is still a debated question. AGB stars synthesise this element and likely contribute significantly to its synthesis in the present-day Universe. However, it…
A perspective on the Milky Way Bulge-Bar as seen from the neutron-capture elements Cerium and Neodymium with APOGEE
J. V. Sales-Silva, K. Cunha, V. V. Smith +28
This study probes the chemical abundances of the neutron-capture elements cerium and neodymium in the inner Milky Way from an analysis of a sample of 2000 stars in the Galact…
Chemical abundances of the young inner-disk open cluster NGC 6705 observed by APOGEE: sodium-rich and not -enhanced
V. Loaiza-Tacuri, K. Cunha, D. Souto +19
Previous results in the literature have found the young inner-disk open cluster NGC 6705 to be mildly -enhanced. We examined this possibility via an independent chemical abundan…
Evidence of Deep Mixing in IRS 7, a Cool Massive Supergiant Member of the Galactic Nuclear Star Cluster
Rafael Guerço, Verne V. Smith, Katia Cunha +9
The center of the Milky Way contains stellar populations spanning a range in age and metallicity, with a recent star formation burst producing young and massive stars. Chemical abu…
Fluorine Abundances in the Galactic Nuclear Star Cluster
Rafael Guerço, Solange Ramírez, Katia Cunha +4
Abundances of fluorine (F), as well as isotopic ratios of O/O, are derived in a sample of luminous young (10--10 yrs) red giants in the Galac…
Fluorine Abundances in the Galactic Disk
Rafael Guerço, Katia Cunha, Verne V. Smith +5
The chemical evolution of fluorine is investigated in a sample of Milky Way red giantstars that span a significant range in metallicity from [Fe/H] -1.3 to 0.0 dex. Fluorine…
Fluorine Abundances in the Globular Cluster M 4
Rafael Guerço, Katia Cunha, Verne V. Smith +6
We present chemical abundances for the elements carbon, sodium, and fluorine in 15 red giants of the globular cluster M 4, as well as six red giants of the globular cluster Cen…
