... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

The complex interplay between regions of massive star formation and their surroundings is a determining component of galaxy evolution. Winds of massive stars and the resulting supernova explosions inject mechanical energy into the interstellar medium, redistributing gas within a galaxy. ... Return to list of thesis topics . ...

HIGHLIGHTS Astronomy highlights First obser vations of SNR 1987A at 12 mm (page 19) One of the principal scientific justifications for the 12-mm upg rade on the Compact Ar ray was to obtain higher resolution imag es of continuum sources, in particular for the radio remnant of the supernova SN 1987A. In October 2001, the first 12-mm image of SN 1987A was obtained using three Compact Ar ray antennas equipped with interim 12-mm receivers. ...

... To avoid extensive numerical calculations in the statistical simulations, we treat the continuous evolution of each binary component as a sequence of a finite number of basic evolutionary states (for example, main sequence, red (super)giant, helium (Wolf-Rayet) star,     hot WD), in which stellar parameters significantly differ from each other. ... Figure 2: Schematic representation of the typical evolutionary track of a massive binary system with normal and compact star stages indicated. ...

What happens to a star heavier than five solar masses? ... Stars about ten solar masses probably behave like our five solar mass star until they reach the end of core-helium burning. ... The Crab nebula was formed after a massive explosion ripped a star apart in 1054. ... Today, the glowing outer layers of the star are still rushing away from a tiny star in the centre. ... An incredible explosion rips through the outer layers of the star, releasing colossal amounts of energy in a supernova explosion. ...

A Canadian and American team of Astronomers have used the 305-m wide Arecibo radio dish, the world's largest and most sensitive radio telescope, to uncover a dozen new super-fast-spinning pulsars. The team directed their search for these rare and exotic stars by pointing the Arecibo radio telescope towards massive star clusters, called Globular Clusters, orbiting our Milky Way galaxy. ... One of the most exotic residents in the Globular cluster system are the millisecond pulsars. ...

... Research . ... A rare hybrid morphology radio galaxy . ... In this project we will be able to investigate the environmental effect on star formation and galaxy evolution in individual galaxies falling into the cluster through radio observations of active galactic nuclei (AGN). Current models of galaxy evolution regulate the star formation rates within the simulated galaxies by invoking radio-mode feedback from AGN. ... Julie.Banfield@anu.edu.au . ...

... Over the past decade and a half, astronomers have used both ground-based and space-based telescopes to discover more than 400 "extrasolar" planets.
