  Several questions:

  1) What seperates novae from non-novae?  Does binary configuration play
     an essential part?

  2) Has binary configuration of "justified novae" been confirmed anyway?

  3) Recurrent novae have a broad spectrum in the sense of the binary
     structure.  Aren't they considered as "novae" with mutiple recorded
     explosions?
