Modeling emission lines of 8 northern planetary nebulae.

NEINER C., ACKER A., GESICKI K. and SZCZERBA R.

Abstract (from CDS):

In order to constrain the nebular density distribution and velocity field, we model nebular lines profiles obtained at very high spectral resolution. The method and computer code applied to 2-3 nebular lines were described in earlier publications. In the present work we analyse 4-11 spectral lines observed simultaneously with the spectrometer ELODIE (R=42000) for 8 planetary nebulae. For five analyzed nebulae with a [WC]-type nucleus, we found highly broadened profiles implying possible turbulent motions.
