New calculations of Solar spectrum resolve decade-long controversy about the Sun’s chemical composition | Max-Planck-Gesellschaft

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 updated results for abundances of different chemical elements, which resolve the conflict. Notably, the Sun contains more oxygen, silicon and neon than previously thought. The methods employed also promise considerably more accurate estimates of the chemical compositions of stars in general.

Sunrise III launches successfully | Max-Planck-Gesellschaft

The Sunrise III solar observatory has been successfully launched. On July 10, 2024, it took off from the Esrange Space Center balloon and rocket base near Kiruna in Sweden on a helium balloon into the stratosphere. Stratospheric winds are now carrying the solar telescope along the Arctic Circle over the Atlantic Ocean to Canada. The telescope will study the active surface of the sun.
