Abstract:
-
We have done calculations modelling the post-AGB evolution. Our modelling
takes into account the evolution of the central star and hydrodynamics
of the dust-gas nebula
formed from the AGB and post-AGB winds. The results allow us to construct
and
discuss a histogram of post-AGB objects with the spectral type. We
show that
important selection effects can be present in the histogram due to
large optical thickness of the nebula in early post-AGB phases. A preliminary
comparison of the modelled histograms with observations suggests that the
typical mass of post-AGB objects is close to 0.6 M$_\odot$.
