Melting/Freezing in Narrow Pores; Dielectric and EPR Studies
We report results of a study of the phenomena associated with melting of nano-phases confined within narrow pores. The study was performed by differential scanning calorimetry, dielectric spectroscopy, nonline...

Observation of Microstructures in Planetary Nebulae
HST images of 5 Planetary nebulae showing small scale structures have been retrieved from the archives. For two PNe, NTT images were also available, and a double channel deconvolution technique applied to comb...

A 3D Kinematic Model of NGC 3242
TAURUS-II imaging Fabry-Perot data in the emission lines of Ha, He II, [O I], [O III] and [N II] have been obtained to study the kinematics of NGC 3242. By studying the kinematic structure in lines of a range ...

An Imaging and Spectroscopic Survey of the Abell Planetary Nebulae
The Abell catalogue of planetary nebulae (PN) are distinguished by their large size, low surface brightness and generally faint central stars. They are thought to be old PN approaching the White Dwarf cooling ...

The Planetary Nebulae in the Sagittarius Dwarf Galaxy
There are 9 dwarf spheroidal galaxies in the neighbourhood of the Galaxy. The last to be discovered is in Sagittarius (Ibata et al 1994), situated at a distance of 25 kpc and is interacting with the Galaxy. It...

[O II] Electron Density Map** applied to NGC 6826
The [O II]3726,3729Å doublet is sensitive to electron densities in the range 100 to 104 cm-3, typical of planetary nebulae, and thus provides an ideal tool for map** the projected density structure. The first u...

Modelling the Expansion of NGC 7027
The high angular resolution and dynamic range of VLA radio continuum map** of planetary nebulae has raised expansion parallax measurement to the most sensitive method for determining PN distances (Hajian et ...
