The 64th TI-FRIS Hub Meeting / 80th FRIS Hub Meeting (Hybrid event)
TI-FRIS Hub Meetings are held once a month at Tohoku University to foster researchers who understand and can utilize the importance of interdisciplinary research across disciplines and institutions.
Common sense and way of thinking cannot be expected among researchers in different fields. The audience is encouraged to ask questions during the presentation to discuss and deepen their understanding. Please participate actively.
・Date & Time: Every Friday of the month except August (16:00-17:00)
・Target Audience: TI-FRIS Fellows, researchers and students from TI-FRIS participating institutions

Presentation Title：
Cosmic Explosions and origins of elements
Abstract：
Where did the elements around us come from? The early universe contained mostly hydrogen and helium, while heavier elements were formed later in stars and stellar explosions. In this talk, I will show how numerical simulations help us study these violent events and the origin of the elements. I will first discuss mergers of neutron stars, which eject neutron-rich matter and produce many heavy elements. I will then discuss the collapse of massive stars, where a newly formed black hole and its surrounding accretion disk can drive powerful explosions and eject newly synthesized elements into space.
