Quantifying Mass Loss of RGB Stars in Globular Clusters with Asteroseismology

Explore groundbreaking research on stellar mass loss through this 20-minute conference talk from Monash University researcher Madeline Howell. Dive into the study of red giant branch (RGB) stars within globular clusters, examining how mass loss affects their evolution and final stellar remnants. Learn about the innovative use of K2 mission photometry and asteroseismology to measure stellar masses with unprecedented accuracy across four globular clusters: M4, M80, M9, and M19. Discover key findings that confirm the relationship between mass loss and metallicity, while uncovering evidence in M4 that challenges traditional mass loss models like Reimers'. Understand how significant mass loss occurs after the RGB luminosity bump, providing crucial insights for improving stellar modeling and our understanding of stellar evolution.
