A Southwest Research Institute-led team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles spectroscopy and helioseismology measurements for the first time. Helioseismology probes the sun’s interior by analyzing the waves that travel through it, while spectroscopy reveals the surface composition based on the spectral signature produced by each chemical element.
Team proposes new solar composition ratios that could reconcile longstanding questions
