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.
A star who's brightness changes is called a variable star.Examples are:AlgolPolarisBetelgeuse.See related link for more information.
A star that pulsates is known as 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. Wikipedia has more information, and you'll find a link to their post below.
Homam (Sometimes Homan) or Zeta Pegasi is a star in the constellation Pegasus.It has a spectral type of B0 so it is blue-white giant.

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.
