Stellar model tests and age determination for RGB stars from the APO-K2 catalogue
G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1
By adopting the recently empirically derived dependence of -elements on instead of the conventionally applied uniform one, we tested the agreement between stellar…
Impact of enhancement on the asteroseismic age determination of field stars. Application to the APO-K2 catalogue
G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1
We investigated the theoretical biases affecting the asteroseismic grid-based estimates of stellar parameters in the presence of a mismatch between the heavy element mixture of obs…
Impact of the uncertainties of and reactions on the He-burning phases of low- and intermediate-mass stars
F. Tognini, G. Valle, M. Dell'Omodarme +2
We estimate the impact on the stellar evolution of the uncertainties in the and the reaction rates [...]. We calculated models of low- and inte…
Stellar model calibrations with the Ai Phe binary system. Open questions about the robustness of the fit
G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1
We explore the robustness of the calibration of stellar models achievable with Ai Phe binary system. By means of the SCEPtER pipeline, we investigated the impact of different assum…
Age and convective core overshooting calibrations in CPD-54 810 binary system. Statistical investigation on the solution robustness
G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1
Relying on precise observations for the CPD-54 810 binary system, we investigate the robustness of the estimated age and convective core overshooting for a system with both stars o…
Uncertainties in asteroseismic grid-based estimates of the ages of halo stars
S. Moser, G. Valle, M. Dell'Omodarme +2
[...] The aim of this paper is to study the precision and theoretical biases in the age determinations of halo stars adopting both asteroseismic and classic observational constrain…
