A Solar cycle correlation of coronal element abundances in Sun-as-a-star observations

Warren, Harry P.; Brooks, David H.; Baker, Deborah +1 more

The elemental composition in the coronae of low-activity solar-like stars appears to be related to fundamental stellar properties such as rotation, surface gravity, and spectral type. Here we use full-Sun observations from the Solar Dynamics Observatory, to show that when the Sun is observed as a star, the variation of coronal composition is highl…
