New calculations of Solar spectrum resolve decade-long controversy about the Sun's chemical composition

Heidelberg, Germany (SPX) May 20, 2022

Astronomers have resolved the decade-long solar abundance crisis: the conflict between the internal structure of the Sun as determined from solar oscillations (helioseismology) and the structure derived from the fundamental theory of stellar evolution, which in turn relies on measurements of the present-day Sun's chemical composition. New calculations of the physics of the Sun's atmosphere yield
