Confronting expansion distances of planetary nebulae with Gaia DR2 measurements
D. Schönberner, M. Steffen
Individual distances to planetary nebulae are of the utmost relevance for our understanding of post-asymptotic giant-branch evolution because they allow a precise determination of…
The evolution of planetary nebulae. V. The diffuse X-ray emission
M. Steffen, D. Schoenberner, A. Warmuth
Observations with space-borne X-ray telescopes revealed the existence of soft, diffuse X-ray emission from the inner regions of planetary nebulae. Although the existing images supp…
Toward better simulations of planetary nebulae luminosity functions
R. H. Mendez, A. M. Teodorescu, D. Schoenberner +2
We describe a procedure for the numerical simulation of the planetary nebulae luminosity function (PNLF), improving on previous work (Mendez & Soffner 1997). Earlier PNLF simulatio…
The evolution of planetary nebulae IV. On the physics of the luminosity function
D. Schoenberner, R. Jacob, M. Steffen +1
The nebular evolution is followed from the vicinity of the asymptotic-giant branch across the Hertzsprung-Russell diagram until the white-dwarf domain is reached, using various cen…
Stellar evolution of low and intermediate-mass stars. IV. Hydrodynamically-based overshoot and nucleosynthesis in AGB stars
F. Herwig, T. Blöcker, D. Schönberner +1
The focus of this study is on the treatment of those stellar regions immediately adjacent to convective zones. The results of hydrodynamical simulations by Freytag et al. (1996, A&…
