[vsnet-alert 9326] GW Lib: superhump period update and evolution

[Taichi Kato]

Dear all,

   The VSNET Collaboration has received 46000+ observations up to now.
The rapid evolution of the superhump period has stopped, and the
object now shows a nearly constant superhump period of 0.053925(4) d,
corresponding to a fractional period excess of 1.1%.
The mean superhump profile shows a sign of a secondary maximum around
phase 0.3.

   The earlier stage with a significantly longer superhump period
has shown to exactly correspond to the stage of rapid growth of
the superhumps.
