Evolution of a Long-Lived Deep-Seated Main-Sequence Magnetic Field During White Dwarf Cooling
Matias Castro-Tapia, Maria Camisassa, Shu Zhang
We study the evolution of white dwarf (WD) magnetic fields that originate from core-convective dynamos during the main-sequence. Using stellar evolution and WD cooling models combi…

Three-component Phase Separation for Ultramassive White Dwarf Models
Matias Castro-Tapia, Andrew Cumming
We investigate phase separation in oxygen-neon (O/Ne) ultramassive white dwarfs (UMWDs). Current stellar evolution codes, such as MESA, only account for s…
