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…
On the formation of DA white dwarfs with low hydrogen contents: Preliminary Results
M. M. Miller Bertolami, L. G. Althaus, A. H. Córsico
Systematic photometric and asteroseismological studies in the last decade support the belief that white dwarfs in the solar neighborhood harbor a broad range of hydrogen-layer cont…
Post-AGB evolution much faster than previously thought
K. Gesicki, A. A. Zijlstra, M. M. Miller Bertolami
For 32 central stars of PNe we present their parameters interpolated among the new evolutionary sequences. The derived stellar final masses are confined between 0.53 and 0.58 $M_\o…
Breaking news from the HST: The central star of the Stingray Nebula is now returning towards the AGB
N. Reindl, T. Rauch, M. M. Miller Bertolami +2
SAO244567 is a rare example of a star that allows us to witness stellar evolution in real time. Between 1971 and 1990 it changed from a B-type star into the hot central star of the…
An asteroseismic constraint on the mass of the axion from the period drift of the pulsating DA white dwarf star L19-2
Alejandro H. Córsico, Alejandra D. Romero, Leandro G. Althaus +6
We employ an asteroseismic model of L19-2, a relatively massive ($M_{\star} \sim 0.75 M_{\sun}$) and hot ( K) pulsating DA (H-rich atmosphere) white dwarf…
On the relevance of bubbles and potential flows for stellar convection
Marcelo M. Miller Bertolami, Maxime Viallet, Vincent Prat +2
Recently Pasetto et al. have proposed a new method to derive a convection theory appropriate for the implementation in stellar evolution codes. Their approach is based on the simpl…
