Helioseismic determination of the solar metal mass fraction
G. Buldgen, A. Noels, V. A. Baturin +5
Context. The metal mass fraction of the Sun Z is a key constraint in solar modelling, but its value is still under debate. The standard solar chemical composition of the late 2000s…
Ionization of heavy elements and the adiabatic exponent in the solar plasma
V. A. Baturin, A. V. Oreshina, W. Däppen +4
Context. The adiabatic exponent is studied as a thermodynamic quantity in the partially ionized plasma of the solar convection zone. Aims. The aim of this study is to underst…
Interpolation of equation-of-state data
V. A. Baturin, W. Däppen, A. V. Oreshina +2
Aims. We use Hermite splines to interpolate pressure and its derivatives simultaneously, thereby preserving mathematical relations between the derivatives. The method therefore gua…
Evolution of lithium abundance in the Sun and solar twins
F. Thevenin, A. V. Oreshina, V. A. Baturin +3
Evolution of the 7Li abundance in the convection zone of the Sun during different stages of its life time is considered to explain its low photospheric value in comparison with tha…
