CAPOS: The bulge Cluster APOGEE Survey VI. Characterizing multiple stellar populations and chemical abundances in the bulge globular cluster NGC 6569

Nicolás Barrera, Sandro Villanova, Doug Geisler +2

Context. The CAPOS project aims to obtain accurate mean abundances and radial velocities for many elements, and it explores the multiple population (MP) phenomenon in Galactic bulg…

The large-scale kinematics of young stars in the Milky Way disc: first results from SDSS-V

Eleonora Zari, Jaime Villaseñor, Marina Kounkel +17

We present a first large-scale kinematic map of 50,000 young OB stars ( K), based on BOSS spectroscopy from the Milky Way Mapper OB program in the on…

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…

Mapping the Distant and Metal-Poor Milky Way with SDSS-V

Vedant Chandra, Phillip A. Cargile, Alexander P. Ji +28

The fifth-generation Sloan Digital Sky Survey (SDSS-V) is conducting the first all-sky low-resolution spectroscopic survey of the Milky Way's stellar halo. We describe the stellar…

The VISCACHA survey XIV. Chemical evolution history of the SMC: The Southern Bridge Clusters

Sasi Saroon, B. Dias, T. Tsujimotto +18

The chemical evolution history of the Small Magellanic Cloud (SMC) is complex and is best understood through a comprehensive analysis of star clusters across its various regions. T…

Abundances of P, S, and K in 58 bulge spheroid stars from APOGEE

B. Barbuy, H. Ernandes, A. C. S. Friaça +25

We have previously studied several elements in 58 selected bulge spheroid stars, based on spectral lines in the H-band. We now derive the abundances of the less-studied elements ph…
