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
Aims. 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 C2 m…
Opacity for realistic 3D MHD simulations of cool stellar atmospheres
A. Perdomo García, N. Vitas, E. Khomenko +4
Context. Realistic 3D time-dependent simulations of stellar near-surface convection employ the opacity binning method for efficient and accurate computation of the radiative energy…
Non-LTE abundance corrections for late-type stars from 2000Å to 3μm: I. Na, Mg, and Al
K. Lind, T. Nordlander, A. Wehrhahn +6
It is well known that cool star atmospheres depart from local thermodynamic equilibrium (LTE). Accurate abundance determination requires taking those effects into account, but the…
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…
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…
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…
