| description | We present preliminary results of our study of a small sample of planetary nebulae in the Galactic Bulge for which high-angular resolution Hubble Space Telescope imaging is available. From this and from archival spectroscopy, we were able to calculate temperatures and luminosities for their central stars. These were then correlated to up-to-date evolutionary tracks found in the literature to help us estimate stellar masses and therefore ages for the central stars. Our current analysis indicates that our sample appears to represent a somewhat mixed population of planetary nebulae central stars, while at least one of the nebulae might have been formed by a more massive progenitor (i.e., <inline-formula> <math display="inline"> <semantics> <mrow> <msub> <mi>M</mi> <mi>ZAMS</mi> </msub> <mo>∼</mo> <mn>4</mn> </mrow> </semantics> </math> </inline-formula> M<inline-formula> <math display="inline"> <semantics> <msub> <mrow></mrow> <mo>⊙</mo> </msub> </semantics> </math> </inline-formula>). |
