Past events

11am–12pm 14 May 2015
The Southern African Large Telescope (SALT) was a relatively cheap (~$20M) 10m class telescope, for which the construction phase was completed, relatively quickly, by late 2005....
11am–12pm 12 May 2015
Despite many decades of progress in understanding the evolution of star formation and stellar populations in galaxies, we have still fundamental questions that have remained...
11am–12pm 7 May 2015
We often describe galaxies at z=0 as a bimodal population. On one side we have gas-rich, star-forming spirals; on the other, passively-evolving, gas-poor, early-types. The former...
11am–12pm 28 April 2015
Molecular clouds in the central 200 pc of the Galaxy (the 'Central Molecular Zone') exhibit different (and more extreme) physical properties than those in the disk, yet because...
7–9pm 24 April 2015
Mount Stromlo Observatory in conjunction with the Canberra Astronomical Society invite the Canberra community to attend our public observing nights of 2015. Come and see the rings...
11am–12pm 23 April 2015
The environment of a galaxy can play a major role in its evolution. Late-type gas-rich galaxies can be transformed into gas-poor early-type galaxies in dense environments....
10–11.30am 18 April 2015
Take a walking tour of the Mount Stromlo Observatory and learn about one of Canberra’s oldest sites. Mount Stromlo Observatory has been carrying out astronomical...
11am–12pm 16 April 2015
One of the major unknowns in the history of Earth is concerned with the effects on the Earth of the Late Heavy Bombardment, documented on the moon during ~3.95-3.85 billion years...
11am–12pm 14 April 2015
Asteroseismology - the study of stellar oscillations - is a powerful tool to probe the structure and evolution of stars. In addition to the large number of newly discovered...
11am–12pm 9 April 2015
Sun-like stars end their lives in a phase of catastrophic mass loss. Between 30% and 80% of the mass of the star is lost in an extreme stellar wind. The ejecta are briefly visible...
11am–12pm 2 April 2015
The upper limit to stellar masses is unclear, as is the relative importance of 'nature' (stellar physics) and 'nurture' (formation environment) to the limit. I will show that...
11am–12pm 31 March 2015
Post-Asymptotic Giant Branch (post-AGB) stars bear signatures of the entire chemical and morphological changes that occur prior to and during the AGB phase of evolution. In our...
11am–12pm 26 March 2015
Local galaxies are in a state of 'energy equipartition' which means that the kinetic energy density equals roughly the thermal one and the magnetic one. Thus, we can deduce that...
2–3pm 24 March 2015
The range of offshore 8m-class telescopes to which Australian astronomers have access is about to undergo significant changes. I will outline the extensive suite of facilities on...
11am–12pm 19 March 2015
Where did Edwin Hubble get his famous tuning fork from? Every astronomer studying galaxies uses Hubble types Sa, Sb, Sc; does anyone know the actual source of the 'Hubble...
2–3pm 18 March 2015
Brian Boyle will give us an update on the Square Kilometre Array project, particularly the recently completed process of re-baselining and the implications for Australia.
11am–12pm 12 March 2015
Interacting binary stars that produce 'fast and faint' transients, thermonuclear and stripped core-collapse supernovae, or merging compact objects play a crucial role in many...
11am–12pm 5 March 2015
The first natural guide star (NGS) and laser guide star (LGS) adaptive optics (AO) systems on 8 to 10 m class telescopes were implemented on the Keck II telescope in 1999 and 2004...
10–11.30am 28 February 2015
Take a walking tour of the Mount Stromlo Observatory and learn about one of Canberra’s oldest sites. Mount Stromlo Observatory has been carrying out astronomical...
11am–12pm 26 February 2015
The early chemical evolution of the Galaxy and the Universe is vital to our understanding of a host of astrophysical phenomena. Since the oldest, most metal-poor stars are relics...
