New Results on R Aquarii
D. R. Goncalves, A. Mampaso, S. Navarro +1
The first results on new optical data for R Aquarii (based on observations obtained with the 2.5m INT, the 2.5m NOT and the 3.5m NTT) are presented. The morphology and kinematics o…
The Physical Parameters and Excitation of Jets and Knots in PNe
D. R. Goncalves, A. Mampaso, R. M. L. Corradi +1
We are carrying out a study of the physical parameters and excitation of low-ionization structures (LIS) in planetary nebulae (PNe). Since the optical morphology and kinematics of…
Characterizing Low-Ionization Structures in PNe
Denise R. Goncalves
Fifty five planetary nebulae containing micro-structures of low-ionization (LIS) are analyzed in this review in terms of LIS morphology, kinematics, and physical and excitation pro…
The physical parameters, excitation and chemistry of the rim, jets and knots of the planetary nebula NGC 7009
Denise R. Goncalves, Romano L. M. Corradi, Antonio Mampaso +1
We present long-slit optical spectra along the major axis of the planetary nebula NGC 7009. These data allow us to discuss the physical, excitation and chemical properties of all t…
