1RXS J232953.9+062814 slow fading continues
Dear Colleagues,
After the rebrightening observed on November 10-11, the star has shown
a steady linear decline at a constant rate of 0.13 mag/d (at least up to
Nov. 18). Such a linear post-superoutburst decline is rather frequently
seen in WZ Sge-type dwarf novae or large-amplitude SU UMa-type dwarf novae,
such as WX Cet (cf. Kato et al. 2001, PASJ 53, 893). Together with the
presence of a post-superoutburst rebrightening, and double-humped light curve
in quiescence, this star seems to bear characteristics similar to those of
WZ Sge-type stars, as well as other peculiar properties already described.
The short-term light curve is still dominated by double-wave humps, with
occasional brightenings (time scale ~1-2 hr), during which humps tend to
become rather unclear.
The VSNET Collaboration team has received many new data, which will be
reviewed later by Uemura-san. We have been also keenly analyzing all
recent Kyoto observations, made on all nights.
Please send any data and information to Uemura-san also
(uemura@kusastro.kyoto-u.ac.jp).
Regards,
Taichi Kato
