Abundance analysis of APOGEE spectra for 58 metal-poor stars from the bulge spheroid
R. Razera, B. Barbuy, T. C. Moura +19
The central part of the Galaxy host a multitude of stellar populations, including the spheroidal bulge stars, stars moved to the bulge through secular evolution of the bar, inner h…
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…
BACCHUS Analysis of Weak Lines in APOGEE Spectra (BAWLAS)
Christian R. Hayes, Thomas Masseron, Jennifer Sobeck +11
Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure their chemical abundanc…
The chemical characterisation of halo substructure in the Milky Way based on APOGEE
Danny Horta, Ricardo P. Schiavon, J. Ted Mackereth +21
Galactic haloes in a -CDM universe are predicted to host today a swarm of debris resulting from cannibalised dwarf galaxies. The chemo-dynamical information recorded in their st…
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…
Rotational modulation of spectroscopic Zeeman signatures in low-mass stars
Ryan C. Terrien, Allison Keen, Katy Oda +24
Accurate tracers of the stellar magnetic field and rotation are cornerstones for the study of M dwarfs and for reliable detection and characterization of their exoplanetary compani…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
Detailed Chemical Abundances for a Benchmark Sample of M Dwarfs from the APOGEE Survey
Diogo Souto, Katia Cunha, Verne V. Smith +16
Individual chemical abundances for fourteen elements (C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are derived for a sample of M-dwarfs using high-resolution near-infrar…
