Query: Post-AGB Evolution in the Large Magellanic Cloud. A Study of the Central
  Stars of Planetary Nebulae   We present medium- and broad-band Hubble Space Telescope (HST) photometry of
a sample of 35 central stars (CSs) of Planetary Nebulae (PNs) in the Large
Magellanic Cloud (LMC). The observations were made with the WFPC2 and STIS
instruments on board the HST. By observing LMC objects, our sample is free of
the distance uncertainty that is the dominate source of error in the
determination of CS luminosities in Galactic PNs. By observing with the HST, we
resolve the nebula and therefore we often detect the CSs unambiguously. We
obtain core masses of 16 of the objects by comparing their positions on the HR
diagram to theoretical evolutionary tracks, once we determine the stellar
effective temperature through Zanstra analysis. This sample of CS masses is the
largest and most reliable set obtained in an extra-Galactic environment. We
find an average mass of 0.65 Msun, though a few of the objects have very high
mass. This average value is consistent with the average mass of the white dwarf
population in the Galaxy. As the immediate precursors of white dwarfs, the
study of the mass distribution of PN CSs should help to constrain the
initial-to-final mass relation within environments of differing metallicity.
Finally, by exploring the physical connections between the star and the nebula,
we establish the importance of the study of PNs in the LMC to constrain the
energy input from the wind during the post-AGB phase.
