Core rotation rates along evolution. Left panel: Average core rotation rate (logarithmic scale) as a function of mixed mode density. Right panel: Average core rotation rate (logarithmic scale) as a function of stellar radius (logarithmic scale). The different colours represent evolutionary tracks with different stellar masses and the different line styles indicate the angular momentum transport mechanisms included as per the legend. The vertical dashed (dotted) grey lines in the left panel indicate the values 𝒩 = 8 (𝒩 = 14), respectively. The grey circles in the right panel indicate the observed core rotation rates from Deheuvels et al. (2014), Triana et al. (2017), Gehan et al. (2018).
