[vsnet-alert 4868] RXJ1450.5+6403 in quiescence

[Daisaku Nogami <nogami@satsuki.kusastro.kyoto-u.ac.jp>]

Dear colleagues,

We reduced our photometric data of RXJ1450.5+6403 (= HS 1450+6403)
obtained on 2000 May 7, 10, and 11.  A period analysis using May
7 and 10 data gives a period estimation of 0.056 d with a large
error due to short coverage, favoring the shorter candidate
(0.0588 d) of the two possibilities indicated by John Thorstensen
(vsnet-alert 4848).  The periodgram suggest the half period
(~0.28 d) to be less possible.

The light curve folded by the period of 0.056 d shows ~0.35-mag
orbital humps and ~0.1-mag secondary hump.  Yes, this is remiscent
of WZ Sge, AL Com, and so on, in quiescence, as Taichi Kato
noted in vsnet-alert 4858.  We can not see any hints of eclipse.

Best regards,
Daisaku Nogami
