Planetary 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 کاملEvolution of PAH Features from Proto- to Planetary Nebulae
With the aim to investigate the overall evolution of UIR band features with hardening of UV radiation (increase of the star’s effective temperature) we have analysed ISO spectra for 32 C-rich stars: 20 proto-planetary nebulae and 12 planetary nebulae with Wolf-Rayet central stars. In this contribution we discuss variations in the peak position of UIR bands among analysed objects, and demonstrat...
متن کاملPhysical Structure of Planetary Nebulae . Ii . Ngc 7662
We present a study of the structure and kinematics of the triple-shell planetary nebula NGC7662 based on long-slit echelle spectroscopic observations and HST archival narrow-band images. The structure of NGC 7662 main nebula consists of a central cavity surrounded by two concentric shells. The bright inner shell has a non-negligible thickness and the highest density in the nebula. The outer she...
متن کاملEnigmatic Low-velocity Jet-like Features in Planetary Nebulae
We are developing a project aimed at studying the physical properties, origin and evolution of low-ionization structures in planetary nebulae. Within this project we have identified a number of pairs of highly collimated low-ionization jet-like features (Gonçalves et al. 2001). In spite of being very similar to real jets, they have the intriguing property of possessing expansion velocities whic...
متن کاملIntracluster Planetary Nebulae
We review the progress of research on intracluster planetary nebulae (IPN). In the past five years, hundreds of IPN candidates have been detected in the Virgo and Fornax galaxy clusters and searches are also underway in poorer galaxy groups. From the observations to date, and applying the known properties of extragalactic planetary nebulae, the intracluster light in Virgo and Fornax: 1) is sign...
