A Study of Cool White Dwarfs in the Sloan Digital Sky Survey Data Release 12

G. Ourique, A. D. Romero, S. O. Kepler +2

In this work we study white dwarfs where to compare the differences in the cooling of DAs and non-DAs and their f…

Evolution and Asteroseismology of Pulsating Low-Mass White Dwarfs

L. M. Calcaferro, A. H. Córsico, L. G. Althaus +2

Many low-mass white dwarfs are being discovered in the field of our galaxy and some of them exhibit -mode pulsations, comprising the extremely low-mass variable (ELMV) stars cla…

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

F. C. De Gerónimo, L. G. Althaus, A. H. Córsico +2

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…

Blue Large-Amplitude Pulsators (BLAPs): possible origin, evolutionary status, and nature of their pulsations

Alejandro H. Córsico, Alejandra D. Romero, Leandro G. Althaus +2

The Blue Large-Amplitude Pulsators (BLAPs) constitute a new class of pulsating stars. They are hot stars with effective temperatures of K and surface grav…

New full evolutionary sequences of H and He atmosphere massive white dwarf stars using MESA

G. R. Lauffer, A. D. Romero, S. O. Kepler

We explore the evolution of hydrogen-rich and hydrogen-deficient white dwarf stars with masses between 1.012 and 1.307 Msun, and initial metallicity of Z=0.02. These sequences are…

The sdA problem - II. Photometric and Spectroscopic Follow-up

Ingrid Pelisoli, S. O. Kepler, D. Koester +3

Subdwarf A star (sdA) is a spectral classification given to objects showing H-rich spectra and sub-main sequence surface gravities, but effective temperature lower than the zero-ag…

Comparing the asteroseismic properties of pulsating pre-extremely low mass white dwarf and delta Scuti stars

Julieta P. Sanchez Arias, Alejandra D. Romero, Alejandro H. Corsico +5

Pulsating extremely low-mass pre-white dwarf stars (pre-ELMV), with masses between ~0.15 Msun and ~0.30 Msun, constitute a new class of variable stars showing g- and possibly p-mod…

On the evolutionary status and pulsations of the recently discovered Blue Large-Amplitude Pulsators (BLAPs)

Alejandra D. Romero, A. H. Córsico, L. G. Althaus +2

The Blue Large-Amplitude Pulsators (BLAPs) constitute a new class of pulsating stars. They are hot stars with effective temperatures of ~30 000 K and surface gravities of log g ~ 4…

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…
