Query: Metallicity effects on the modified wind momentum of CSPN   Recent investigations on the central stars of planetary nebulae (CSPN)
indicate that the masses based on model atmospheres can be much larger than the
masses derived from theoretical mass-luminosity relations. Also, the dispersion
in the relation between the modified wind momentum and the luminosity depends
on the mass spread of the CSPN, and is larger than observed in massive hot
stars. Since the wind characteristics probably depend on the metallicity, we
analyze the effects on the modified wind momentum by considering the dispersion
in this quantity caused by the stellar metallicity. Our CSPN masses are based
on a relation between the core mass and the nebular abundances. We conclude
that these masses agree with the known mass distribution both for CSPN and
white dwarfs, and that the spread in the modified wind momentum can be
explained by the observed metallicity variations.
