Explore the future of axion astrophysics in this comprehensive 1-hour 15-minute lecture by Oscar Straniero at the Galileo Galilei Institute. Delve into the potential of using stars as laboratories to study axions, examining energy conservation equations and theoretical errors. Investigate globular clusters and HR diagrams, discussing the necessary theoretical models and parameters for accurate analysis. Learn about the historical evolution of axion research, including the importance of massive stars, supergiants, and supernovae in this field. Discover the latest results from combined analyses and error assessments, and gain insights into the role of satellites like Vera Rubin in advancing our understanding of axions in astrophysics.
