Variable Star Observers are amateur and professional astronomers who monitor and study stars that change brightness over time. These stars, known as variable stars, can fluctuate in brightness due to various factors, including pulsations, eruptions, or interactions with other celestial bodies. Observers use telescopes and specialized equipment to collect data on these changes. The observations made by Variable Star Observers contribute to our understanding of stellar behavior and evolution. They often collaborate with organizations like the American Association of Variable Star Observers (AAVSO) to share their findings and help create a comprehensive database of variable star activity.
