Magnetic field breakout in ultramassive crystallizing white dwarfs
Ultramassive white dwarfs with masses $M\gtrsim 1.1\,{\rm M}_\odot$ probe extreme physics near the Chandrasekhar limit. Despite the rapid increase in observations, it is still unclear how many harbour carbon-oxygen (CO) versus oxygen-neon (ONe) cores. The origin of these white dwarfs and their strong magnetic fields - single stellar evolution or a stellar merger - is another open question. The steep mass-radius relation of the relativistic ultramassive white dwarfs shortens their crystallizatio…
