Higher metal abundances do not solve the solar problem
G. Buldgen, P. Eggenberger, A. Noels +4
Context. The Sun acts as a cornerstone of stellar physics. Thanks to spectroscopic, helioseismic and neutrino flux observations, we can use the Sun as a laboratory of fundamental p…
The chemical compositions of multiple stellar populations in the globular cluster NGC 2808
M. Carlos, A. F. Marino, A. P. Milone +8
Pseudo two-colour diagrams or Chromosome maps (ChM) indicate that NGC 2808 host five different stellar populations. The existing ChMs have been derived by the Hubble Space Telescop…
The impact of carbon and oxygen abundances on the metal-poor initial mass function
Piyush Sharda, Anish M. Amarsi, Kathryn Grasha +5
Star formation models predict that the metal-poor initial mass function (IMF) can be substantially different from that observed in the metal-rich Milky Way. This changeover occurs…
Titanium abundances in late-type stars I. 1D non-local thermodynamic equilibrium modelling in benchmark dwarfs and giants
J. W. E. Mallinson, K. Lind, A. M. Amarsi +4
The titanium abundances of late-type stars are important tracers of Galactic formation history. However, abundances inferred from Ti I and Ti II lines can be in stark disagreement…
3D non-LTE iron abundances in FG-type dwarfs
A. M. Amarsi, S. Liljegren, P. E. Nissen
Spectroscopic measurements of iron abundances are prone to systematic modelling errors. We present 3D non-LTE calculations across 32 STAGGER-grid models with effective temperatures…
