abstract:Mira variables , named after the star Mira, are a class of pulsating variable stars characterized by very red colors, pulsation periods longer than 100 days, and amplitudes greater than one magnitude in infrared and 2.5 magnitude at visual wavelengths.
In addition, star colour is simulated for noticeably red, blue and yellow stars, along with the changing brightness of three variable stars Algol, Mira and Delta Cephei.
