Magnetic origin of the discrepancy between stellar limb-darkening models and observations (2024)
Journal Article
Kostogryz, N. M., Shapiro, A. I., Witzke, V., Cameron, R. H., Gizon, L., Krivova, N. A., …Valenti, J. (in press). Magnetic origin of the discrepancy between stellar limb-darkening models and observations. Nature Astronomy, https://doi.org/10.1038/s41550-024-02252-5

Stars appear darker at their limbs than at their disk centres because at the limb we are viewing the higher and cooler layers of stellar photospheres. Yet, limb darkening derived from state-of-the-art stellar atmosphere models systematically fails to...
