The Pristine survey -- XII: Gemini-GRACES chemo-dynamical study of newly discovered extremely metal-poor stars in the Galaxy
Collin L. Kielty, Kim A. Venn, Federico Sestito +16
High-resolution optical spectra of 30 metal-poor stars selected from the \Pristine\ survey are presented, based on observations taken with the Gemini Observatory GRACES spectrograp…
Chemical diversity among A-B stars with low rotational velocities: non-LTE abundance analysis
L. Mashonkina, T. Ryabchikova, S. Alexeeva +2
We present accurate element abundance patterns based on the non-local thermodynamic equilibrium (non-LTE, NLTE) line formation for 14 chemical elements from He to Nd for a sample o…
Mono-enriched stars and Galactic chemical evolution -- Possible biases in observations and theory
Camilla Juul Hansen, Andreas Koch, Lyudmila Mashonkina +9
A long sought after goal using chemical abundance patterns derived from metal-poor stars is to understand the Galactic chemical evolution (GCE) and to pin down the nature of the fi…
The Pristine Inner Galaxy Survey (PIGS) II: Uncovering the most metal-poor populations in the inner Milky Way
Anke Arentsen, Else Starkenburg, Nicolas F. Martin +19
Metal-poor stars are important tools for tracing the early history of the Milky Way, and for learning about the first generations of stars. Simulations suggest that the oldest meta…
Influence of Collisions with Hydrogen on Titanium Abundance Determinations in Cool Stars
T. M. Sitnova, S. A. Yakovleva, A. K. Belyaev +1
We performed the non-local thermodynamic equilibrium (non-LTE) calculations for Ti I-II with the updated model atom that includes quantum-mechanical rate coefficients for inelastic…
Non-LTE line formation for Si I-II-III in A-B stars and the origin of Si II emission lines in iota Her
Lyudmila Mashonkina
A comprehensive model atom was developed for Si I-II-III using the most up-to-date atomic data available so far. Based on the non-local thermodynamic equilibrium (non-LTE = NLTE) l…
