A Guide to Variable Stars and how to observe them
Thursday, 18th September 2014 (19:45 - 22:00)
Variable stars are stars whose light output,for some reason, varies. We often plot light curves showing the brightness (magnitude) of the star versus time, to see how the light output is changing. Where there is a regular periodicity to the variation, we can specify a period for the star, which is simply the length of time for the star to go through one cycle. The range of variation can be from barely detectable millimagnitudes to several whole magnitudes.
