Abstract:
Manganese (Mn) is a key Fe-group element, commonly employed in stellar
population and nucleosynthesis studies to explore the role of SN Ia.We
have developed a new non-local thermodynamic equilibrium (NLTE) model
of Mn, including new photo-ionisation cross-sections and new
transition rates caused by collisions with H and H- atoms. We
applied the model in combination with onedimensional (1D) LTE model
atmospheres and 3D hydrodynamical simulations of stellar convection to
quantify the impact of NLTE and convection on the line formation. We
show that the effects of NLTE are present in MnI and, to a lesser
degree, in MnII lines, and these increase with metallicity and with
the effective temperature of a model. Employing 3D NLTE radiative
transfer, we derive a new abundance of Mn in the Sun,
A(Mn)=5.52±0.03dex, consistent with the element abundance in CI
meteorites. We also applied our methods to the analysis of three
metal-poor benchmark stars. We find that 3D NLTE abundances are
significantly higher than 1D LTE. For dwarfs, the differences between
1D NLTE and 3D NLTE abundances are typically within 0.15 dex, however,
the effects are much larger in the atmospheres of giants owing to
their more vigorous convection. We show that 3D NLTE successfully
solves the ionisation and excitation balance for the RGB star HD
122563 that cannot be achieved by 1D LTE or 1D NLTE modelling. For HD
84937 and HD 140283, the ionisation balance is satisfied, however, the
resonance MnI triplet lines still show somewhat lower abundances
compared to the high-excitation lines. Our results for the benchmark
stars confirm that 1D LTE modelling leads to significant systematic
biases in Mn abundances across the full wavelength range from the blue
to the IR. We also produce a list of Mn lines that are not
significantly biased by 3D and can be reliably, within the 0.1 dex
uncertainty, modelled in 1D NLTE.
