FIZZLERS

• Normal Stellar Evolution ====> Type II Supernovae

• Fizzlers: What and Who are they?

• Gravitational Wave (GW) Emission
  Finn & Evans -- less than 10^-8 Mc² in GW
  Centrella & coworkers -- up to 10^-3 Mc² in GW
  

  Why the gross difference between the results?

• Bar Instabilities:
  
  

  Bar Mode structure for an n=1.5, n'=0, T/|W|=0.327 polytrope.	Gravity wave pattern for a rotating nonaxisymmetric central disturbance.

  
  The bar forms very quickly and settles into what appears to be a stable state. If future simulations verify this conjecture, then fizzlers will produce significant gravitational wave emission and may be viable targets for LIGO.
