Magnetic Field Evolution for Crystallization-driven Dynamos in C/O White Dwarfs

We investigate the evolution of magnetic fields generated by the crystallization-driven dynamo in carbon–oxygen white dwarfs (WDs) with masses ≲1.05 M _⊙ . We use scalings for the dynamo to demonstrate that the initial magnetic field strength ( B _0 ) has an upper limit that depends on the initial c...
