Angular dimensions of planetary nebulae
- R. Tylenda, N. Siódmiak, S. Górny, R. Corradi, H. E. Schwarz
- Physics, Geology
- 24 April 2003
We have measured angular dimensions of 312 planetary nebulae from their images obtained in H α (or H α + [NII]). We have applied three methods of measurements: direct measurements at the 10% level…
Abundances in the Galactic bulge: results from planetary nebulae and giant stars
- C. Chiappini, S. Górny, G. Stasińska, B. Barbuy
- Physics
- 2 December 2008
Context. Our understanding of the chemical evolution (CE) of the Galactic bulge requires the determination of abundances in large samples of giant stars and planetary nebulae (PNe). Studies based on…

V4332 Sagittarii revisited
- R. Tylenda, L. Crause, S. Górny, M. Schmidt
- Physics
- 9 December 2004
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 and unclear. We…

- Physics
- 12 May 2009
Aims. We present a homogeneous set of spectroscopic measurements secured with 4-m class telescopes for a sample of 90 planetary nebulae (PNe) located in the direction of the Galactic bulge. Methods.…

- Physics
- 19 January 2006
Received ; accepted Abstract. 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,…
An atlas of images of Planetary Nebulae
- S. Górny, H. E. Schwarz, R. Corradi, H. Winckel
- Physics
- 1 April 1999
A catalogue of narrowband CCD images of 100 southern and 1 northern Planetary Nebulae is presented. The data are images taken in the light of the H α , H β , [OIII]500.7 nm, and [NII]658.4 nm lines.…
Infrared properties of planetary nebulae with (WR) central stars
- S. Górny, G. Stasińska, R. Szczerba, R. Tylenda
- Physics, Geology
- 1 October 2001
We have gathered from the literature near and mid infrared (photometric and spectroscopic) data for Galactic planetary nebulae, with special attention to planetary nebulae surrounding Wolf-Rayet type…
Statistics of planetary nebulae with [WR] central stars
- S. Górny
- Physics
- 2001
The status of planetary nebulae with Wolf-Rayet type central stars([WR] PN) remains one of the most important problems inthe investigation of planetary nebulae. We cannot claim to understand…
