Our speaker this month is Dr. Alison Sills from the Department of Physics and Astronomy at McMaster University, who will be speaking to us on her area of expertise: stellar formation:
Secrets from Stellar Nurseries: The Early Lives of Star Clusters
We know that stars are born out of large clouds of gas and dust. Most stars are born in groups. But what happens next? Do the siblings stick together, moving through the universe together all their lives, or do they disperse and move out of their birth neighbourhood as soon as they can? What influence do they have on their nursery cloud? What if another family of stars is born right next door — do they get together? Using a combination of observations and simulations, I will explore what we know about the early evolution of star clusters.
Dr Alison Sills studies weird stars in unusual places. The stars that interest her have had a strange encounter during their life, such as a collision with another star or an interaction with their binary companion. These events happen more often in dense stellar clusters. Dr Sills uses a variety of computational tools to model the formation and evolution of these clusters and their stellar populations. Dr Sills grew up in Toronto and attended the University of Western Ontario for her BSc before studying at Yale University for her PhD. After postdoctoral positions at The Ohio State University and the University of Leicester in the UK, she returned to Ontario to take up a faculty position at McMaster University in 2001. A full professor at McMaster since 2012, Dr Sills has also served as Associate Dean of Science and Associate Dean of Graduate Studies, and is currently the Chair of Physics & Astronomy. She has published over 125 research papers with over 6000 citations, has supervised over 50 students & postdoctoral fellows, and has directly managed over $2M in research grants. Dr Sills is involved in the astronomical community at the national and international level, through her membership in Canadian Astronomical Society committees, the Canadian Institute for Theoretical Astrophysics council, the Canadian Telescope Time Allocation Committee, and an International Astronomical Union steering committee. She has reviewed grant, scholarship, and telescope time applications for granting agencies in half a dozen countries, and been involved with organization of 30 international conferences since 2000. Dr Sills also spends time on outreach activities to bring astronomy to the public, to support women and other underrepresented groups in STEM, and to bring scientists to elementary schools.
Following Dr. Sills’ presentation, we will have a short intermission, followed by door prizes, and then our monthly Sky This Month presentation.
The address for our meeting is the parish hall at St. Matthews-on-the-Plains Anglican Church, 126 Plains Road East, Burlington, ON L7T 2C3. Doors will open at 7:00PM, with the meeting beginning promptly at 7:30
