listen to the pronunciation of değişken yıldız
Turkish - English
variable star
Any star whose brightness varies
A star whose brightness varies because of internal changes or periodic eclipsing of mutually revolving stars. Star whose observed brightness varies noticeably in intensity. Pulsating variables expand and contract in cycles, pulsating rhythmically in brightness and size. Explosive variables include novas and supernovas, which brighten rapidly due to sudden outbursts of radiant energy; the increased brightness lasts a short time, followed by relatively slow dimming. Eclipsing variable stars are variable only because light from one star is blocked by another in Earth's direction. Hundreds of thousands of variable stars are known. See also binary star; Cepheid variable; flare star; pulsar; T Tauri star
