The study of globular star clusters has been an active area of research for more than half a century, but every year new science emerges from the investigation of the properties of these old stellar systems. Some recent exciting discoveries about stellar evolution, stellar dynamics, and black hole physics have tremendously enriched our understanding of these fascinating stellar systems.
Curious to know more? Have a look at the review article (for a non-specialist audience) I wrote this summer for “Il Nuovo Saggiatore”, the Journal of the Italian Society of Physics.
