Chemical Abundances of Planetary Nebulae in the Sagittarius Dwarf Elliptical Galaxy

Spectrophotometry and imaging of the two planetary nebulae He 2-436 and Wray 16423, recently discovered to be in the Sagittarius dwarf elliptical galaxy, are presented. Wray 16-423 is a high excitation planetary nebula (PN) with a hot central star. In contrast He 2-436 is a high density nebula with a cooler central star and evidence of local dust, the extinction exceeding that for Wray 16-423 b...

The Planetary Nebula Luminosity Function

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. We review the method’s precision, and use it to show that the distance scale defined by Cepheids and the Surface Brightness Fluctuation method is likely too large by...

HST / NICMOS Imaging of the Planetary Nebula

Images of Hubble 12 were obtained with the HST/NICMOS instrument in the F110W, F164N, and F166N filters of NIC1, and the F160W, F187N, F190N, F212N, F215N filters of NIC2. The images show the structure of the inner “torus” and lobes much clearer than previous ground-based images. In particular, the [Fe II] lobes are clearly resolved and shown to be distinct from the H2 emission structures. Appa...
