“Variable Stars and Their Stories”
Dr. Stella Kafka, Executive Director, American Association
of Variable Star Observers (AAVSO)
Variable stars have always been the most intriguing (and fun) targets for observers, professional and amateur alike. Stellar variability provides unique insights in critical stages of stellar evolution, helps determine distances to nearby galaxies, and adds to our understanding of explosion physics and the Milky Way’s chemical enrichment. I will introduce some of the most common aspects of stellar variability and their significance in astrophysics. I will discuss their common light curves identifiers and present work by AAVSO observers, leading to cutting-edge scientific discoveries throughout the years. Finally, I will discuss how you can participate in variable star observations from your back yard, contributing to the AAVSO International Database and cutting-edge science.
Dr. Stella Kafka is the Executive Director and CEO of the American Association of Variable Star Observers (AAVSO), an international organization focusing on engaging professional and amateur astronomers in science. Within the auspices of the AAVSO, Dr Kafka is working towards enabling individuals from all backgrounds to actively participate in research projects, building a community of science-savvy citizens who work collectively to understand some of the most dynamic phenomena in the universe.
