摘要 (Abstract): 

Around the turn of the last century, star clusters of all kinds were considered ‘simple’ stellar populations. Over the past decade, this situation has changed dramatically. At the same time, star clusters are among the brightest stellar population components and, as such, they are visible out to much greater distances than individual stars, even the brightest, so that understanding the intricacies of star cluster composition and their evolution is imperative for understanding stellar populations and the evolution of galaxies as a whole. In this review of where the field has moved to in recent years, we place particular emphasis on the properties and importance of the effects of rapid stellar rotation, and the presence of multiplicity among the red-giant-branch populations in Magellanic Cloud star clusters with ages up to a few billion years.

主讲人简介 (Speaker's CV): 

Prof. Richard de Grijs obtained  his PhD from the University of Groningen (Netherlands) in 1997. He joined the Kavli Institute for Astronomy and Astrophysics at Peking University (China) in September 2009 as a full professor. In March 2018, he moved to Macquarie University in Sydney (Australia) as Associate Dean (Global Engagement). He was awarded the 2012 Selby Award for excellence in science by the Australian Academy of Science, as well as a 2013 Visiting Academy Professorship at Leiden University by the Royal Netherlands Academy of Arts and Sciences. He was awarded a 2017 Erskine award by the University of Canterbury (New Zealand) in part for his engagement with undergraduate students.

His research interests focus on (i) star clusters and stellar populations; (ii) the astronomical distance scale/variable stars; and (iii) the history of maritime navigation.
