At typical speaking fundamental frequencies (~80 - 300 Hz or so) the analys F. or High-Precision Photometry : IRAC Performance. IRAC Best Performance. Observations reach close to the photon-limit for binning over timescales of up to several hours. Correlated noise is increasingly important for larger bins. USNO-B1 1289-0181948. Blake Head. What is a Variable Star?. A variable star is simply a star that changes in brightness over a set period of time (generally). This can happen in eclipsing binaries, where a star passes in front of another companion star, and pulsating variables, in which a star physically pulsates inwards and out due to instabilities within its core. .
