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 $\lesssim1.05\ M_{\odot}$. 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 convection zone size ($R_{\mathrm{out},0}$) and …
