Magnetic white dwarfs from DESI
Larissa L. Amorim, S. O. Kepler, Alejandra D. Romero
A significant fraction of white dwarfs, the degenerate remnants of low- and intermediate-mass stars, host strong magnetic fields; yet, the origin and evolution of these magnetic fi…

Evolution and formation of ultramassive white dwarf stars: The case for a 9Msun progenitor
Ana S. R. Antonini, Alejandra D. Romero, S. O. Kepler
We study the full evolution of a 1.313 Msun white dwarf star that descended from a 9 Msun main-sequence progenitor with an initial metallicity of Z=0.02. Using MESA r24.08.01, we c…

Pulsating low-mass white dwarfs in the frame of new evolutionary sequences VI. Thin H-envelope sequences and asteroseismology of ELMV stars revisited
Leila M. Calcaferro, Alejandro H. Córsico, Leandro G. Althaus +2
Some low-mass white-dwarf (LMWD) stars with H atmospheres show long-period g-mode pulsations, comprising the class of pulsating WDs called extremely low-mass variable (ELMV) stars.…
