Observing bright pulsating white dwarfs with PLATO: A new window into the late stages of stellar evolution
Murat Uzundag, Alejandro H. Corsico, Nicholas Jannsen +17
We present the scientific case for exploiting the capabilities of the PLATO mission to study bright pulsating white dwarfs across a wide spectral range, including hydrogen-deficien…
Asteroseismological analysis of the polluted ZZ Ceti star G29-38 with TESS
Murat Uzundag, Francisco C. De Gerónimo, Alejandro H. Córsico +15
G\,2938 (TIC~422526868) is one of the brightest () and closest (\,pc) pulsating white dwarfs with a hydrogen-rich atmosphere (DAV/ZZ Ceti class). It was obser…
WD J004917.14252556.81, the Most Massive Pulsating White Dwarf
Mukremin Kilic, Alejandro H. Córsico, Adam G. Moss +3
We present APO and Gemini time-series photometry of WD J004917.14252556.81, an ultramassive DA white dwarf with K and . We detect variabili…
Uncertainties in the 12C+12C reaction rate and their impact on the composition of ultra-massive WDs
F. C. De Gerónimo, M. M. Miller Bertolami, M. Catelan +1
Stars with initial masses 7 Msun . MZAMS . 9 Msun reach temperatures high enough to ignite C under degenerate conditions after the end of He-core burning (Garcia-Berro & Iben 1994)…
Asteroseismology of ZZ Ceti stars with full evolutionary white dwarf models. II. The impact of AGB thermal pulses on the asteroseismic inferences of ZZ Ceti stars
Francisco C. De Gerónimo, Leandro G. Althaus, Alejandro H. Córsico +2
The thermally pulsing phase on the asymptotic giant branch (TP-AGB) is the last nuclear burning phase experienced by most of low and intermediate mass stars. During this phase, the…
Asteroseismology of ZZ Ceti stars with fully evolutionary white dwarf models: I. The impact of the uncertainties from prior evolution on the period spectrum
Francisco C. De Gerónimo, Leandro G. Althaus, Alejandro H. Córsico +2
ZZ Ceti stars are pulsating white dwarfs with a carbon-oxygen core build up during the core helium burning and thermally pulsing Asymptotic Giant Branch phases. Through the interpr…
The evolution of white dwarfs resulting from helium-enhanced, low-metallicity progenitor stars
Leandro G. Althaus, Francisco C. De Gerónimo, Alejandro H. Córsico +2
Some globular clusters host multiple stellar populations with different chemical abundance patterns. This is particularly true for Centauri, which shows clear evidence of a hel…
