Speaker Name(s): Dr. Alison Sills, PhD
Description: Globular clusters are spherical clusters of many thousand stars, thought to be some of the simplest objects in the universe. There is increasing evidence that there is more than one stellar generation in globular clusters – not just a single “baby boom”, but a complex interplay of stellar birth, death, and rebirth. I will discuss some of the implications of – and problems with – this new scenario. www.physics.mcmaster.ca/people/faculty/Sills_AI_h.html This lecture is co-sponsored by the Royal Astronomical Society of Canada – Toronto Centre
