This variation may be caused by a change in emitted light or by something partly blocking the light, so variable stars are classified as either: [ 1 ]
- Types of Variable Stars: Cepheid, Pulsating and CataclysmicA variable star is, quite simply, a star that changes brightness. A star is considered variable if its apparent magnitude (brightness) is altered in any way from our perspective on Earth.
- What is a variable star? - EarthSkyBottom line: A variable star is one whose brightness changes regularly. Here we discuss the different kinds of variable stars and what causes their brightness variations.
- Types of Variable Stars: A Guide for Beginners - aavsoVariable stars are divided into two main categories: Intrinsic: physical changes within or on the surface of the star cause the brightness of the star to vary. Extrinsic: outside occurrence (s), not directly affecting the star’s properties, cause the star’s apparent brightness to vary.
- Variable star | Pulsating, Light Curve, Magnitude | Britannicavariable star, any star whose observed light varies notably in intensity. The changes in brightness may be periodic, semiregular, or completely irregular. A brief treatment of variable stars follows. For full treatment, see star: Variable stars.
