Abundances in the Galactic bulge: results from planetary nebulae and giant stars
C. Chiappini, S. Gorny, G. Stasinska +1
Our understanding of the chemical evolution of the Galactic bulge requires the determination of abundances in large samples of giant stars and planetary nebulae (PNe). We discuss P…
Planetary nebulae with emission-line central stars
K. Gesicki, A. A. Zijlstra, A. Acker +3
The kinematic structure of a sample of planetary nebulae, consisting of 23 [WR] central stars, 21 weak emission line stars (wels) and 57 non-emission line central stars, is studied…
V4332 Sagittarii revisited
R. Tylenda, L. A. Crause, S. K. Gorny +1
The eruption of V4332 Sgr discovered in February 1994 shows striking similarities to that of V838 Mon started in January 2002. The nature of these eruptions is, however, enigmatic…
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,…
Angular dimensions of planetary nebulae
R. Tylenda, N. Siodmiak, S. K. Gorny +2
We have measured angular dimensions of 312 planetary nebulae from their images obtained in Halpha (or Halpha + [NII]). We have applied three methods of measurements: direct measure…
COMPARATIVE STUDY OF A [WC 6] NUCLEUS WITH OTHER EMISSION-LINES NUCLEI OF PLANETARY NEBULAE
A. Acker, S. K. Gorny, F. Cuisinier
The central star (CSPN) of the planetary nebula M 1-25 (PN G 4.9+4.9) is classified as a [WC 6] star, the only CSPN of this subclass known at this time. A comparison with the other…
