Morpho-kinematic Modeling of Gaseous Nebulae with Shape
We present a powerful new tool to analyse and disentangle the 3-D geometry and kinematic structure of gaseous nebulae. The method consists in combining commercially available digital animation software to simulate the 3-D structure and expansion pattern of the nebula with a dedicated, purpose built rendering software that produces the final images and long slit spectra which are compared to the...
متن کاملA deep kinematic survey of planetary nebulae in the Andromeda Galaxy using the Planetary Nebula Spectrograph
We present a catalogue of positions, magnitudes and velocities for 3300 emission-line objects found by the Planetary Nebula Spectrograph in a survey of the Andromeda Galaxy, M31. Of these objects, 2615 are found likely to be planetary nebulae (PNe) associated with M31. The survey area covers the whole of M31’s disk out to a radius of 1.5. Beyond this radius, observations have been made along th...
متن کاملPlanetary Nebulae
Planetary nebulae (PNe) can be used to trace intermediate and old stellar populations in galaxies and the intracluster medium out to approximately 20 Mpc. PNe can be easily identified with narrow-band surveys, and their chemical abundances and radial velocities can be measured with multi-slit or multi-fiber spectrographs. We briefly review what has been accomplished to date, and include tables ...
متن کاملModeling emission lines of 8 northern planetary nebulae
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=42 000) for 8 planetary nebulae. For five ...
متن کاملMicrostructures of Planetary Nebulae with Large Telescopes
Planetary nebulae (PNe) are known to possess a variety of small-scale structures that are usually in a lower ionization state than the main body of the nebulae. The morphological and kinematic properties of these low-ionization structures (LISs) vary from type to type in the sense that LISs can appear in the form of pairs of knots, filaments, jets, and isolated features moving with velocities t...
