Modeling He-rich subdwarfs through the hot-flasher Scenario
M. M. Miller Bertolami, L. G. Althaus, K. Unglaub +1
We present 1D numerical simulations aimed at studying the hot-flasher scenario for the formation of He-rich subdwarf stars. Sequences were calculated for a wide range of metallicit…
The pulsation modes of the pre-white dwarf PG 1159-035
J. E. S. Costa, S. O. Kepler, D. E. Winget +74
PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…
The importance of the remnant's mass for VLTP born again times. Implications for V4334 Sgr and V605 Aql
Marcelo M. Miller Bertolami, Leandro G. Althaus
We present numerical simulations of the very late thermal pulse (VLTP) scenario for a wide range of remnant masses. We show that, by taking into account the different possible remn…
Modeling He-rich subdwarfs through the Hot-Flasher scenario: First Results
Marcelo M. Miller Bertolami, Leandro G. Althaus
We present first results from evolutionary simulations aimed at exploring the Hot-Flasher scenario for the formation of H-deficient subdwarf stars. The two types of late hot flashe…
White Dwarf Luminosity and Mass Functions from Sloan Digital Sky Survey Spectra
Steven DeGennaro, Ted von Hippel, D. E. Winget +4
We present the first phase in our ongoing work to use Sloan Digital Sky Survey (SDSS) data to create separate white dwarf (WD) luminosity functions for two or more different mass r…
The born again (VLTP) scenario revisited: The mass of the remnants and implications for V4334 Sgr
M. M. Miller Bertolami, L. G. Althaus
We present 1-D numerical simulations of the very late thermal pulse (VLTP) scenario for a wide range of remnant masses. We show that by taking into account the different possible r…
