On the existence of warm H-rich pulsating white dwarfs
Leandro G. Althaus, Alejandro H. Córsico, Murat Uzundag +8
The possible existence of warm ( K) pulsating DA white dwarf (WD) stars, hotter than ZZ Ceti stars, was predicted in theoretical studies more than 30 yr ago…
Asteroseismological analysis of the ultra-massive ZZ Ceti stars BPM~37093, GD~518, and SDSS~J0840+5222
Alejandro H. Córsico, Francisco C. De Gerónimo, María E. Camisassa +1
Ultra-massive hydrogen-rich (DA) white dwarfs (WD) are expected to have a substantial portion of their cores in a crystalline state at the effective temperatures characterizing the…
Gaia DR2 white dwarfs in the Hercules stream
Santiago Torres, Carles Cantero, María E. Camisassa +5
We analyzed the velocity space of the thin and thick-disk Gaia white dwarf population within 100 pc looking for signatures of the Hercules stellar stream. We aimed to identify thos…
The effects of Ne sedimentation and metallicity on the local 40 pc white dwarf luminosity function
Jordi Tononi, Santiago Torres, Enrique García-Berro +3
We analyze the effect of the sedimentation of Ne on the local white dwarf luminosity function by studying scenarios under different Galactic metallicity models. We make use…
