Time - Starting at 7:00 PM
One of the topics to be covered will be Variable stars by Sean Curry.
There are a number of reasons why variable stars change their brightness. Pulsating variables, for example, swell and shrink due to internal forces. An eclipsing binary will dim when it is eclipsed by a faint companion, and then brighten when the occulting star moves out of the way. Some variable stars are actually extremely close pairs of stars, exchanging mass as one star strips the atmosphere from the other.
The study of variable stars offers us a change to do real science while observing through the AAVSO. Citizen Scientists have cataloged over 37 million observations. Since 1911 the AAVSO has been collecting data on thousands of variables. Check them out at:
