New models for the evolution of Post-Asymptotic Giant Branch stars and Central Stars of Planetary Nebulae

Understand

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• The two grids of models presently available are based on outdated micro- and macro-physics and do not agree with each other.
• We study the timescales of post-AGB and CSPNe in the context of our present understanding of the micro- and macro-physics of stars.
• We want to assess whether new post-AGB models, based on the latter improvements in TP-AGB modeling, can help to understand the discrepancies between observation and theory and within theory itself.
