AAQ Special Interest Sections
Variable StarsThe Variable Star Section was formed in June 1998 to educate and assist members to observe stars that change in brightness. Members are encouraged to submit their observations to international databases (AAVSO, RASNZ etc) where the data is used by professional astronomers to determine how stars behave and evolve over time. Variable star observing is one of the few fields where amateur astronomers can make a real contribution to the science of astronomy. An Introduction To Variable Stars Methods For The Visual Observation Of Variable Stars A few of the brighter variable stars that are visible in binoculars have been selected by the AAQ for regular monitoring and the development of our own database. The light curve for R Carinae, one of the AAQ selected stars, is shown below for the period January 2000 to December 2004. The light curve plots the change in brightness (visual magnitude) against time (Julian Date).
A brief introduction to variable stars is provided below. Further information on variable stars can also be obtained from the excellent website maintained by the American Association Of Variable Star Observers. If you would like to find out more about this interesting and rewarding field of astronomy or would like some variable star observing training please contact the Variable Star Section Director. |
