 lay a crucial role in studies of cosmic chemical evolution\, stellar evolu
 tion\, nucleosynthesis\, and the accelerating expansion of the Universe. T
 hey are widely believed to originate from thermonuclear explosions of whit
 e dwarfs in binary systems. However\, despite extensive theoretical and ob
 servational efforts over the past decades\, the nature of their progenitor
  systems and the exact explosion mechanisms remain poorly understood. This
  talk will present recent progress in constraining the progenitors and exp
 losion mechanisms of Type Ia supernovae from both theoretical and observat
 ional perspectives\, with a focus on key observables at different evolutio
 nary and explosion stages\, including supernova rates and delay-time distr
 ibutions\, pre-explosion companion stars\, ejecta–companion interaction\
 , circumstellar material interaction\, surviving companion stars\, and the
  properties of supernova remnants.Biography:Zhengwei Liu is a research pro
 fessor at the Yunnan Observatories\, Chinese Academy of Sciences (CAS)\, a
 nd currently serves as the Director of the Yunnan Key Laboratory of Supern
 ova Research. He obtained Ph.D. degree in Astrophysics from the University
  of Chinese Academy of Sciences in 2013. From 2011 to 2013\, he was a join
 t doctoral student at the Max Planck Institute for Astrophysics (MPA) in M
 unich\, Germany. He subsequently conducted postdoctoral research at the Ar
 gelander Institute for Astronomy (AIfA)\, University of Bonn\, from 2013 t
 o 2017. In November 2017\, he joined the Binary Population Synthesis Group
  at the Yunnan Observatories\, CAS. His research interests mainly focus on
  supernovae\, binary star evolution\, and computational astrophysics.\n\nh
