The theoretical pulsation spectra of hot B subdwarfs. Static and evolutionary STELUM models
N. Guyot, V. Van Grootel, S. Charpinet +3
Context. The Kepler and TESS space missions have revealed the rich gravity (g-)mode pulsation spectra of many hot subdwarf B (sdB) stars in detail. These spectra exhibit complex be…
On the Spectral Evolution of Hot White Dwarf Stars. IV. The Diffusion and Mixing of Residual Hydrogen in Helium-rich White Dwarfs
A. Bédard, P. Bergeron, P. Brassard
In the framework of our extensive modeling study of the spectral evolution of white dwarfs, we present here a new set of detailed calculations of the transport of residual hydrogen…
On the Spectral Evolution of Hot White Dwarf Stars. III. The PG 1159DODBDQ Evolutionary Channel Revisited
A. Bédard, P. Bergeron, P. Brassard
We continue our comprehensive theoretical investigation of the spectral evolution of white dwarfs based on sophisticated simulations of element transport. In this paper, we focus o…
On the Spectral Evolution of Hot White Dwarf Stars. II. Time-dependent Simulations of Element Transport in Evolving White Dwarfs with STELUM
A. Bédard, P. Brassard, P. Bergeron +1
White dwarf stars are subject to various element transport mechanisms that can cause their surface composition to change radically as they cool, a phenomenon known as spectral evol…
Toward a systematic cartography of the chemical stratification inside white dwarfs from deep asteroseismic probing of ZZ Ceti stars
S. Charpinet, N. Giammichele, P. Brassard +5
DA-type white dwarfs account for 80% of all white dwarfs and represent, for most of them, the ultimate outcome of the typical evolution of low-to-intermediate mass stars. Their int…
Asteroseismic cartography of hydrogen-deficient white dwarfs
N. Giammichele, S. Charpinet, G. Fontaine +4
We present the results of the asteroseismic analysis of the hydrogen-deficient white dwarf PG 0112+104 from the -2 field. Our seismic procedure using the forward method bas…
