1RXP J113123+4322.5 superhump period change
Dear Colleagues,
We have received new data sets from Nyrola team (Arto Oksanen), Nogami-san
(Hida observatory). The new Kyoto and RIKEN data are being analyzed.
The new data have confirmed the positive period derivative (period
lengthening) of the superhumps! The mean dot(P)/P = +1.2x10^(-5) up to now.
The superhump profile sometimes varies, and sometimes show secondary
maxima. Further continuous observations are strongly encouraged!
Regards,
Taichi Kato
