The Nature of Kink MHD Waves in Magnetic Flux Tubes
We examine the nature of MHD kink waves. This is done by determining the frequency, the damping rate and the eigenfunctions of MHD kink waves for three widely...
The Nature of Low-Ionization Microstructures in Planetary Nebulae
We present a gallery with some of the most interesting microstructures of low-ionization found in planetary nebulae (PNe). A rich zoo of knots, filaments, jets...
The Nature of Low-Ionization Microstructures in PNe
We discuss here the nature of a rich zoo of knots, filaments, jets and jet-like systems, located--in terms of morphology and kinematics--either inside or...
The Local Group provides an interesting and representative sample of galaxies in the rest of the Universe. The high accuracy with which many problems can be...
The Nature, Purpose and Future of Conference Proceedings
Published conference proceedings have been called both a great advancement and a despicable curse for astronomy. In reality, they simply fill a niche that any...
Near-Infrared J H K images are presented for a small sample of HII galaxies observed at UKIRT. Based on NIR colours, comparison with the stellar population...
