ALHkazeista

ALHkazeista is a designation used by the Astronomical League for a variable star located in the constellation Cassiopeia. The Astronomical League's variable star section, often abbreviated as AL, is a program that encourages amateur astronomers to observe and report on variable stars. The "H" in the designation typically indicates that the star is a Cepheid variable, a type of pulsating star whose period of pulsation is directly related to its intrinsic luminosity. The "kazeista" part is a unique identifier assigned to this particular star within the AL program.

Variable stars are stars whose brightness fluctuates over time. This variation can be caused by several factors, including changes in the star's internal structure, eclipses by a companion star, or pulsations. Cepheid variables are particularly important in astronomy because their predictable relationship between pulsation period and luminosity allows astronomers to measure distances to other galaxies. Observing and cataloging these variations helps astronomers understand stellar evolution and the structure of the universe. ALHkazeista, like other stars observed through the Astronomical League's program, contributes to a growing database of variable star behavior, aiding both amateur and professional research.
