High-precision abundances of elements in solar-type stars. Evidence of two distinct sequences in abundance-age relations
P. E. Nissen, J. Christensen-Dalsgaard, J. R. Mosumgaard +3
HARPS spectra with signal-to-noise ratios S/N > 600 at 6000 A were analysed with MARCS model atmospheres to obtain 1D LTE abundances of C, O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Sr…
On the connection between galactic downsizing and the most fundamental galactic scaling relations
E. Spitoni, F. Calura, M. Mignoli +3
In their evolution, star-forming galaxies are known to follow scaling relations between some fundamental physical quantities, such as the mass-metallicity and the main sequence rel…
Galactic Archaeology with asteroseismic ages. II. Confirmation of a delayed gas infall using Bayesian analysis based on MCMC methods
E. Spitoni, K. Verma, V. Silva Aguirre +1
With the wealth of information from large surveys and observational campaigns in the contemporary era, it is critical to properly exploit the data to constrain the parameters of Ga…
Systematic Differences in Spectroscopic Analysis of Red Giants
Ditte Slumstrup, Frank Grundahl, Victor Silva Aguirre +1
A spectroscopic analysis of stellar spectra can be carried out using different approaches; different methods, line lists, atomic parameters, solar abundances etc. The resulting atm…
2D chemical evolution model: the impact of galactic disc asymmetries on azimuthal chemical abundance variations
E. Spitoni, G. Cescutti, I. Minchev +5
Galactic disc chemical evolution models generally ignore azimuthal surface density variation that can introduce chemical abundance azimuthal gradients. Recent observations, however…
