Dear Dr. Kato,

I think that it is too early to discuss in details this unconfirmed
result. I just wanted to point out the possible important implications.
Anyway, I guess that the main source of orbital variation at this stage 
is probably the white dwarf, and the variation would be caused by the
irradiated light from the companion. Variations associated with the
accretion disc might be possible as well. For this nova, at the moment
these are only speculations.
