Hydrogen Ionization Inside the Sun
V. A. Baturin, S. V. Ayukov, A. V. Oreshina +4
Hydrogen is the main chemical component of the solar plasma, and H-ionization determines basic properties of the first adiabatic exponent . Hydrogen ionization remarkably diff…

In-depth analysis of solar models with high-metallicity abundances and updated opacity tables
G. Buldgen, A. Noels, R. Scuflaire +10
Due to the high quality constraints available for the Sun, we can carry out combined analyses using neutrino, spectroscopic and helioseismic observations. Such studies lay the grou…

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…
