Session details: Sunday, 2016-03-27 04:30:00, LT106 Abstract The 29 June 2015 occultation of a 12th magnitude star by Pluto only two weeks out from the New Horizons spacecraft flyby presented a unique opportunity to test models of the structure of Pluto’s atmosphere based on earlier occultations against actual spacecraft observations. The occultation was successfully observed…
Presenter(s): Various Session details: Saturday, 2024-03-29 22:00:00, STAR Abstract The Central West Astronomical Society and NACAA welcome you to Parkes for our 31st event. We hope you enjoy it. We would like to acknowledge the Wiradjuri people who are the traditional custodians of the land on which we are meeting. We pay our respect to…
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…
Presenter(s): Bernard Heathcote Affiliation(s): RASNZ, RAS Session details: Saturday, 2016-03-26 00:30:00, LT101 Abstract Scientifically useful spectroscopy by amateurs, which generally means medium/high resolution spectra taken with a slit spectrograph, has been well established in Europe for at least ten years but in the southern hemisphere, mainly Australia, it has only had a couple of active…
Presenter(s): Stephen Broderick Affiliation(s): St Ursula's College, Toowoomba Session details: Sunday, 2024-03-31 05:30:00, STAR Abstract After working on Tycho Brahe’s Mar’s data for several years, Kepler was able to determine that the orbit of Mars was elliptical. Kepler correctly inferred that all planets travel in elliptical orbits. The eccentricity of the Earth’s orbit took hundreds…
Presenter(s): Tom Richards Affiliation(s): Variable Stars South Session details: Saturday, 2014-04-19 01:00:00, New York Abstract It’s well known that eclipsing binaries provide the only direct way of measuring absolute stellar masses, radii, sizes, luminosities and distances – all together. That alone provides powerful tests for theories of stellar structure and evolution, as well as extending…
