A grid of Non-LTE line-blanketed atmosphere structures and synthetic spectra for subdwarfs
Thayse A. Pacheco, Ronaldo S. Levenhagen, Marcos P. Diaz +1
We present an update of the grid of detailed atmosphere models and homogeneous synthetic spectra for hot, high-gravity subdwarf stars. High-resolution spectra and synthetic photome…
A Grid of Synthetic Spectra for Subdwarfs: Non-LTE line-blanketed atmosphere models
Thayse A. Pacheco, Marcos P. Diaz, Ronaldo S. Levenhagen +1
A new grid of detailed atmosphere model spectra for hot and moderately cool subdwarf stars is presented. High-resolution spectra and synthetic photometry are calculated in the rang…
Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
A comparative analysis of the observed white dwarf cooling sequence from globular clusters
Fabíola Campos, P. Bergeron, A. D. Romero +8
We report our study of features at the observed red end of the white dwarf cooling sequences for three Galactic globular clusters: NGC\,6397, 47\,Tucanae and M\,4. We use deep colo…
