SEMI-EMPIRICAL WHITE DWARF INITIAL-FINAL MASS RELATIONSHIPS: A THOROUGH ANALYSIS OF SYSTEMATIC UNCERTAINTIES DUE TO STELLAR EVOLUTION MODELS
- M. Salaris, A. Serenelli, A. Weiss, M. M. Bertolami
- Physics
- 22 July 2008
Using the most recent results about white dwarfs (WDs) in ten open clusters, we revisit semiempirical estimates of the initial-final mass relation (IFMR) in star clusters, with emphasis on the use of… Expand
New cooling sequences for old white dwarfs
- I. Renedo, L. Althaus, +4 authors E. García-Berro
- Physics
- 12 May 2010
We present full evolutionary calculations appropriate for the study of hydrogen-rich DA white dwarfs. This is
done by evolving white dwarf progenitors from the zero-age main sequence, through the… Expand
Toward ensemble asteroseismology of ZZ Ceti stars with fully evolutionary models
- A. Romero, A. Córsico, L. Althaus, S. O. Kepler, B. G. Castanheira, M. M. Bertolami
- Physics
- 29 September 2011
ZZ Ceti stars form the most numerous group of degenerate variable stars. They are otherwise normal DA (H-rich atmospheres) white dwarfs that exhibit pulsations. Here, we present an… Expand
The born-again (very late thermal pulse) scenario revisited: The mass of the remnants and implications for V4334 Sgr
- M. M. Bertolami, L. Althaus
- Physics
- 5 June 2007
We present 1D 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 remnant masses, the… Expand
New evolutionary calculations for the born again scenario
- M. M. Bertolami, L. Althaus, A. Serenelli, J. A. Panei
- Physics
- 14 November 2005
We present evolutionary calculations to describe the born-again scenario for post-AGB remnant stars of 0.5842 and 0.5885 $M_{\odot}$. Results are based on a detailed treatment of the physical… Expand
Revisiting the axion bounds from the Galactic white dwarf luminosity function
- M. M. Bertolami, B. Melendez, L. Althaus, J. Isern
- Physics
- 30 June 2014
It has been shown that the shape of the luminosity function of white dwarfs (WDLF) is a powerful tool to check for the possible existence of DFSZ-axions, a proposed but not yet detected type of… Expand
The diffusion-induced nova scenario: CK Vul and PB8 as possible observational counterparts
- M. M. Bertolami, L. Althaus, C. Olano, Noelia Jimenez
- Physics
- 28 March 2011
We propose a scenario for the formation of DA white dwarfs with very thin helium buffers. For these stars we explore the possible occurrence of diffusion-induced CNO-flashes during their early… Expand
New models for the evolution of Post-Asymptotic Giant Branch stars and Central Stars of Planetary Nebulae
- M. M. Bertolami
- Physics
- 13 December 2015
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 two grids of models presently available are… Expand
Limits on the neutrino magnetic dipole moment from the luminosity function of hot white dwarfs
- M. M. Bertolami
- Physics
- 1 February 2014
Context. Recent determinations of the white dwarf luminosity function (WDLF) from very large surveys have extended our knowledge of the WDLF to very high luminosities. This, together with the… Expand
