SUMMARY:Exploding stars and catastrophic collisions - Kate Maguire (Trinit
 y College Dublin)
DTSTART:20220203T160000Z
DTEND:20220203T170000Z
UID:TALK169409@talks.cam.ac.uk
CONTACT:Dr. David Murphy
DESCRIPTION:Supernovae (and stellar collisions) are the incredibly luminou
 s (and not so luminous) deaths of stars that play a vital role in chemical
  enrichment\, galaxy feedback mechanisms\, and our understanding of stella
 r evolution. In particular\, Type Ia supernovae\, the explosions of white 
 dwarfs in binary systems\, are vital for constraining the cosmological par
 ameters. In this talk\, I will focus on the latest results on the progenit
 ors and explosion mechanisms of Type Ia supernovae from the state-of-the-a
 rt transient survey\, the Zwicky Transient Facility\, and describe how the
 ir diversity may impact future precision measurements of dark energy. I wi
 ll also highlight recent advances in the related area of stellar collision
 s\, which are testing the boundaries of current theoretical models\, as we
 ll as discuss the link to kilonovae from neutron-star mergers (with and wi
 thout associated gravitational-wave detections).\n
