Morphologies of the Nebulae around "born-again" Central Stars of Planetary Nebulae
S. Kimeswenger, A. A. Zijlstra, P. A. M. van Hoof +5
While in the past spherodicity was assumed, and still is used in modeling of most nebulae, we know now that only a small number of planetary nebulae (PNe) are really spherical or a…
Symmetry and Asymmetry in "born again" Planetary Nebulae
S. Kimeswenger, A. A. Zijlstra, P. A. M. van Hoof +4
While in the past spheroidicity was assumed, and still is used in modeling of most nebulae, we know now that only a small number of planetary nebulae (PNe) are really spherical or…
The progenitor of the 'born-again' core V605 Aql and the relation to its younger twin V4334 Sgr
M. F. M. Lechner, S. Kimeswenger
We derived the properties of V605 Aql before the final helium flash pulse by studying its surrounding PN A58. Photoionizing models of our spectral data together with a new distance…
The early stages of NOVA Oph 2003 (V2573 Oph)
S. Kimeswenger, M. F. M. Lechner
Intermediate resolution spectroscopy of NOVA Oph 2003 (V2573 Oph), which was first detected March 21th 2003 but reported July 19th} 2003, obtained 19th to 23rd of July is presented…
Optical Spectroscopy of IRAS 02091+6333
S. Kimeswenger, A. Bacher, M. Emprechtinger +8
We present a detailed spectroscopic investigation, spanning four winters, of the asymptotic giant branch (AGB) star IRAS 02091+6333. Zijlstra & Weinberger (2002) found a giant wall…
