Variable stars are stars whose brightness changes over time due to intrinsic or extrinsic factors. Intrinsic variables, like Cepheid and Mira variables, undergo changes in their own properties, such as pulsations or eruptions. Extrinsic variables, such as eclipsing binaries, have their brightness altered by external factors, like one star passing in front of another. These stars are important for studying stellar processes and measuring distances in the universe.

What is the period of the variable star betelgeuse?
Betelgeuse is a semi-regular variable star, meaning it does not have a consistent period like a regular variable star. Its brightness fluctuates irregularly over periods of months to years.

What is a variable star?
A variable star (or pulsating star) is a star that an earth observer sees as changing in luminosity over time. This variation in brightness may be something the star is "doing itself" because of changes in its nucleosynthetic processes, or it may be due to the passage of dust clouds or the like between the star and the observer.

No, it is a continuous process but not a continuous variable. The magnitude of star-shine, across all stars is a continuous variable. The magnitude of a star's shine over time is a continuous variable.
