Dear all,
The Department of Physics Cordially Invites you to the Following Colloquium:
Title: Evolution and Fate of Massive Stars
Speaker: Norhasliza Yusof, Department of Physics, Faculty of Science, Universiti Malaya
Date: Friday May 26th 3:00 - 4:00 pm
Venue: BSFB, Department of Physics
Abstract:
Massive and very massive stars have tremendous impact in the cosmic evolution. The nucleosynthesis both during their advanced stages and their final explosion likely contribute greatly to the overall enrichment of the Universe. Their extreme conditions lead also to very important radiative and mechanical feedback effects, from local to cosmic scale. In order to determine their fate, it is important to determine what is the final masses, for example for low metallicities massive or very massive stars, it can retain huge core masses and this could bring the possibility as the candidate of PISNe progenitors. Pair-instability supernovae (PISNe) are very luminous explosions of massive, low-metallicity stars. They can potentially be observed out to high redshifts due to their high explosion energies, thus providing a probe of the Universe prior to reionization.
About the Speaker:
Dr Norhasliza Yusof is a theoretical astrophysicist working as Senior Lecturer at Department of Physics, Universiti Malaya. She obtained her PhD in Nuclear Astrophysics under Commonwealth Split Site Scholarship with Universiti Malaya and Keele University, UK. Her research area is in stellar structure and evolution of massive stars particularly in the fate of the very massive stars. One of the major highlights of her work the determination of the mass and fate of the most massive stars known to date. Dr Norhasliza Yusof actively collaborates with various stellar physics research groups around the world where she is one of the team working in updating and computing Geneva stellar evolution grids.
Thank you.
