Ultra-massive hydrogen-rich (DA spectral type) white dwarf (WD) stars ($M_{\star} > 1M_{\odot}$) coming from single-star evolution are expected to harbor cores made of $^{16}$O and $^{20}$Ne, resulting from semi-degenerate carbon burning when the pro

The impact of pre-white dwarf evolution on the pulsational properties and asteroseismological inferences of ZZ Ceti stars

Autor: De Gerónimo, F. C., Althaus, L. G., Córsico, A. H., Romero, A. D., Kepler, S. O.

ZZ Ceti stars are pulsating white dwarfs with a carbon-oxygen core (or possibly ONe for the most massive stars) build up during the core helium burning (CHeB) and thermally pulsing Asymptotic Giant Branch (TP-AGB) phases. Through the interpretation o

Probing the structure of Kepler ZZ Ceti stars with full evolutionary models-based asteroseismology

Autor: Romero, Alejandra D., Córsico, A. H., Castanheira, B., De Gerónimo, F. C., Kepler, S. O., Koester, D., Kawka, A., Althaus, L. G., Hermes, J. J., Bonato, C., Gianninas, A.

We present an asteroseismological analysis of four ZZ Ceti stars observed with \emph{Kepler}: GD 1212, SDSS J113655.17+040952.6, KIC 11911480 and KIC 4552982, based on a grid of full evolutionary models of DA white dwarf stars. We employ a grid of ca

Salinization reduces the osmotic potential of soil solutions and promotes the accumulation of toxic ions (Na+ and Cl-) in plants, causing nutritional imbalance and yield reductions. Thus, the objective of the present study was to evaluate foliar conc
