Convection and rotation boosted prescription of magnetic braking application to the formation of extremely low-mass white dwarfs
(2021) [Artículo de periódico]Extremely low-mass white dwarfs (ELM WDs) are the result of binary evolution in which a low-mass donor star is stripped by its companion leaving behind a helium-core white dwarf (WD). We explore the formation of ELM WDs ... -
Mysterious, variable, and extremely hot : white dwarfs showing ultra-high excitation lines : I. Photometric variability
(2021) [Artículo de periódico]Context. About 10% of all stars exhibit absorption lines of ultra-highly excited (UHE) metals (e.g., O viii) in their optical spectra when entering the white dwarf cooling sequence. This is something that has never been ... -
TIC 378898110 : a bright, short-period AM CVn binary in TESS
(2023) [Artículo de periódico]AM CVn-type systems are ultracompact, helium-accreting binary systems that are evolutionarily linked to the progenitors of thermonuclear supernovae and are expected to be strong Galactic sources of gravitational waves ...
