Presenter(s): Col Bembrick Affiliation(s): CWAS, VSS, SASI Session details: Posters Abstract Astrophysical modelling of four southern contact eclipsing binaries, using Binary Maker 3. Biography Col became interested in amateur astronomy about 1957 – the Sputnik era. Over the years he has graduated from visual observing to photoelectric photometry; to CCD imaging for variable star observing….
Presenter(s): Judith Bailey Affiliation(s): BAS ASV Session details: Posters Abstract Computer software must adjust for the hemisphere it is being used in. The historic use of nomenclature for the solstices and equinoxes and associated terms originated in the northern hemisphere. Given the state of digital technology and varied seasons across the Earth, a universal approach…

Session details: Posters Abstract Collaborative observations of Near Earth Asteroid (436724) 2011 UW158 recently revealed that it was a superfast rotator asteroid. The extensive data and the light curves obtained spanning over wide Phase Angle range of 17 to 90 degrees allow us to derive an accurate H and G parameters and also shape of…
Affiliation(s): Astronomical Society of Victoria Session details: Posters Abstract Reconstruction of the Great Melbourne Telescope began in 2009 at Museum Victoria. Weekly workshop sessions since then have been attended by a team of about a dozen active volunteers from the Astronomical Society of Victoria.

Affiliation(s): VSS Session details: Posters Abstract Most Cepheids are massive stars which evolve rather quickly compared to low-mass stars. One way of studying this evolution is by tracking changes in the pulsation period as shown with epochs of maxima fitted to an O-C diagram. Members of Variable Stars South and its predecessors have been active…
