Carbon in J0815+4729: Casting A Shadow of Doubt on the Interpretation of CH Absorption in the Most Primitive Stars
Junbo Zhang, Carlos Allende Prieto, Yeisson Osorio +7
We revisit the carbon abundance in the primitive iron-poor star J0815+4729 ([Fe/H] 5.49). J0815+4729 is so carbon-enhanced and oxygen-rich that, in addition to CH and C$_{2}…
Accurate Metallicities for Very Metal-Poor Stars from the Ca~II Infrared Triplet
Y. Osorio, D. S. Aguado, C. Allende-Prieto +2
The Ca~II H \& K lines are among the few features available to infer the metallicity of extremely metal-poor stars from medium-resolution spectroscopy. Unfortunately, these lines c…
Understanding the angular momentum evolution of T Tauri and Herbig Ae/Be stars
Giovanni Pinzón, Jesús Hernández, Javier Serna +8
We investigate a sample of 6 Herbig Ae/Be stars belonging to the Orion OB1 association, as well as 73 low mass objects, members of the Orionis cluster, in order to explore the…
TLUSTY and SYNSPEC Users's Guide IV: Upgraded Versions 208 and 54
Ivan Hubeny, Carlos Allende Prieto, Yeisson Osorio +1
We present a brief description of the newly upgraded versions of the programs TLUSTY, version 208, and SYNSPEC, version 54. TLUSTY is used to generate model stellar atmospheres or…
The APOGEE Data Release 16 Spectral Line List
Verne V. Smith, Dmitry Bizyaev, Katia Cunha +15
The updated H-band spectral line list (from λ15,000 - 17,000Å) adopted by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) for the SDSS IV Data Release 16 (DR16)…
Probing 3D and NLTE models using APOGEE observations of globular cluster stars
T. Masseron, Y. Osorio, D. A. García-Hernández +3
Hydrodynamical (or 3D) and non-local thermodynamic equilibrium (NLTE) effects are known to affect abundance analyses. However, there are very few observational abundance testsof 3D…
