Planetary Nebulae have very repeatable luminosity distributions,and this uniformity is the key to the technique. (1993) showed that, shockingly, the absolute luminosity of the bright-end cutoff of the [O III ] λ 5007 planetary nebula luminosity function (PNLF) was the same (to within a few percent) for all early-type stellar populations. 1 0 obj We also discuss some of the physics underlying the phenomenon, and present clues as why the technique is so resilient.AB - The [O III] λ5007 planetary nebula luminosity function (PNLF) occupies an important place on the extragalactic distance ladder: it is the only standard candle that can be applied to all the large galaxies of the Local Supercluster. stream << endobj /Kids [6 0 R 7 0 R 8 0 R 9 0 R 10 0 R]
