Importance of fingering convection for accreting white dwarfs in the framework of full evolutionary calculations: the case of the hydrogen-rich white dwarfs GD133 and G29-38
F. C. Wachlin, G. Vauclair, S. Vauclair +1
A large fraction of white dwarf stars shows photospheric chemical composition polluted by heavy elements accreted from a debris disk. Such debris disks result from the tidal disrup…
A Type II Supernova Hubble diagram from the CSP-I, SDSS-II, and SNLS surveys
T. de Jaeger, S. González-Gaitán, M. Hamuy +15
The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in…
Galactic structure in the outer disk: the field in the line of sight to the intermediate-age open cluster Tombaugh 1
Giovanni Carraro, Joao Victor Sales Silva, Christian Moni Bidin +1
We employ optical photometry and high-resolution spectroscopy to study a field toward the open cluster Tombaugh 1, where we identify a complex population mixture, that we describe…
Evolution of redback radio pulsars in globular clusters
O. G. Benvenuto, M. A. De Vito, J. E. Horvath
We study the evolution of close binary systems composed of a normal, intermediate mass star and a neutron star considering a chemical composition typical of that present in globula…
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…
New models for the evolution of central stars of planetary nebulae: Faster and Brighter
Marcelo M. Miller Bertolami
The post-asymptotic giant branch (AGB) phase is arguably one of the least understood phases of the evolution of low- and intermediate- mass stars. The recent post-AGB evolutionary…
