Variation of magnetic field intensity with mode density, used as a proxy for stellar evolution. Four different studies are represented in the plot. The arrows pointing upwards represent lower limits to the field intensity while red, while vertical error bars represent the lower and upper limits of the magnetic fields for stars that only show two l = 1 mode components. The grey dotted line at 𝒩 = 9.87 represents the upper limit in evolution reachable in this study (calculated using Δν = 10 μHz and the relevant values for ΔΠ₁ and ν_max obtained from the degeneracy sequence and seismic scaling laws).
