The populations of planetary nebulae in the direction of the Galactic bulge
S. K. Gorny, G. Stasinska, A. V. Escudero +1
We have observed 44 planetary nebulae (PNe) in the direction of the Galactic bulge, and merged our data with published ones. We have distinguished, in the merged sample of 164 PNe,…
On the importance of the few most massive stars: the ionizing cluster of NGC 588
Luc Jamet, Enrique Perez, Miguel Cervino +3
We present the results of a double analysis of the ionizing cluster in NGC 588, a giant HII region (GHR) in the outskirts of the nearby galaxy M33. For this purpose, we obtained gr…
A close binary nucleus in the most oxygen-poor planetary nebula PN G 135.9+55.9
G. H. Tovmassian, R. Napiwotzki, M. G. Richer +3
We report FUSE and new deep optical spectroscopic observations of PN G 135.9+55.9, the most oxygen-poor planetary nebula located in the Galactic halo. These observations allow us t…
What drives the Balmer extinction sequence in spiral galaxies? Clues from the Sloan Digital Sky Survey
G. Stasinska, A. Mateus, L. Sodre +1
Using spectra of normal emission line galaxies from the First Data Release of the Sloan Digital Sky Survey (SDSS) we have investigated the relations between the extinction $C({\rm…
