[vsnet-campaign 1086] Re: [vsnet-alert 6221] Re: WZ Sge: superhump period change
Dear Colleagues,
I was comparing the true superhump period quoted in vsnet-alert 6221,
see below, with that of the orbital superhumps such as quoted in e.g., IAU
Circ. 7672:
Orbital superhump period: 0.056652+/-0.000006 day = 81.579+/-0.009 min
True superhump period : 0.057157+/-0.00077 day = 82.3 +/-1.1 min
Statistically speaking the the "true" superhump period is not yet
significantly different from the orbital superhump period...
But I guess that it will certainly become significant in the next days
when more superhumps come in!
Regards,
Erik Kuulkers
