TmzV85: rare eclipsing SU UMa in superoutburst!
TmzV85が驚くべきことに深い食を伴うSU UMa型であることが判明しました。
北天では、HT Cas, DV UMa等数える程しかなく、その中でも最も明るい方の天体
になると思われます。今後の詳細な観測が極めて期待されます。

TmzV85 eclipsing SU UMa-type dwarf nova in superoutburst!!!
>From the data obtained last night ([vsnet-alert 4035]),
we discovered that TmzV85 is SU UMa-type dwarf nova with eclipse.
The light curve obtained last night clearly shows two superhumps
and two eclipses. The eclipse is deep (1.3 mag), the duration of
eclipse is about 15 min. The orbital period estimated from these
two eclipses is 0.0736 day. The superhump amplitude is about 0.5 mag.
This observarion confirms that TmzV85 belongs to a rare class of deeply
eclipsing SU UMa-type dwarf novae.
We started tonight observation on TmzV85 at 10:00 (UT).
We plan 10-hour observation tonight.
We will undertake an intensive observing campaign on
this object, as we have had a very successful one in
QY Per and DV UMa (in preparation for ongoing publications).
Please post timely to vsnet-alert confirmatory observations,
new findings, the progress of the outburst and observations.
Longer observations are strongly encouarged to precisely determine the
physical parameters of the object. Collaborating observations should
be sent (as usual) to uemura@kusastro.kyoto-u.ac.jp.
We will set up a special page on TmzV85, as we have had on
DV UMa and QY Per.
Regards,
Makoto Uemura and Taichi Kato
