V585 Lyr: first determination of the period change
Dear Collagues,
The VSNET Collaboration has further received new data from Jochen Pietz,
Rudolf Novak and Tom Krajci. The best superhump period determined up to
now is 0.06022 d.
As expected from the shortness of the superhump period, there is already
evidence of positive period change (disregarding the earliest evolution
phase). The preliminary superhump period derivative is at an order of
dot(P)/P = +6x10^(-5). More detailed analysis is in progress.
Further observations are strongly encouraged!
Regards,
Taichi Kato
VSNET Collaboration team
