1RXS J232953.9+062814: positive Pdot system
Dear Colleagues,
Based on 17 superhump maxima timings reported up to now, we have
detected (2 sigma) a period increase of superhumps. The mean period
derivative is dot{P}/P = 6x10^(-5). Although this is smaller than that
observed in V485 Cen, we have confirmed that this second V485 Cen-type
object also shows an increase of the superhump period, in contrast to
most of long-period SU UMa-type dwarf novae (see also Kato (2002) PASJ
in press, for a table and figure of SU UMa-type Pdot).
Further analysis using newly analyzed observations is in progress.
Regards,
Taichi Kato
