DESCRIPTION:Type Ia supernovae are thermonuclear explosions of white dwarf
 s. However\, we don't know how the explosion actually takes place. A singl
 e white dwarf cannot explode\, so it must gain mass from either another wh
 ite dwarf via merging\, or from another star via mass transfer in a binary
  system. The nature of the progenitor is still debated. Also\, there are m
 any ways for the thermonuclear explosion itself. A key to distinguish betw
 een these theoretical scenarios may be the measurement of the ejected mass
 . In the talk I will review the possible progenitor and explosion models\,
  and show some recent results from my group on ejecta mass measurements.\n
 About the speaker:  Dr. Joszef Vinko is an associate professor and senior
  researcher at the University of Szeged and Konkoly Observatory in Hungary
 . He is also a long-term collaborator with the supernova group at UT Austi
 n.  He works on many aspects of observing and modeling supernovae\, from 
 detailed studies of nearby and ordinary supernovae\, to the most extreme a
 nd distant explosions in the universe.\nIn the OKC:  Feb 2nd-3rd (examine
 r in a PhD defense on the morning of Feb 2nd)\, in the SU astronomy corrid
