Magnetohydrodynamic simulations of A-type stars: Long-term evolution of core dynamo cycles

[Context] Early-type stars have convective cores due to a steep temperature gradient produced by the CNO cycle. These cores can host dynamos and the generated magnetic fields may be relevant in explaining the magnetism observed in Ap/Bp stars.
