Photometric study of new southern SU UMa-type dwarf novae and candidates: V877 Ara, KK Tel and PU CMa
T. Kato, R. Santallo, G. Bolt +10
We photometrically observed three dwarf novae V877 Ara, KK Tel and PU CMa. We discovered undisputed presence of superhumps in V877 Ara and KK Tel, with mean periods of 0.08411(2) d…
Two X-Ray Bright Cataclysmic Variables with Unusual Activities: GZ Cnc and NSV 10934
T. Kato, P. A. Dubovsky, R. Stubbings +6
We report on a discovery of unexpected activities in two X-ray bright dwarf novae. GZ Cnc showed an anomalous clustering of outbursts in 2002, in contrast to a low outburst frequen…
The Nature of V359 Centauri Revealed: New Long-Period SU UMa-Type Dwarf Nova
T. Kato, R. Stubbings, P. Nelson +12
We detected four outbursts of V359 Cen (possible nova discovered in 1939) between 1999 and 2002. Time-resolved CCD photometry during two outbursts (1999 and 2002) revealed that V35…
Rapid Optical Fluctuations in the Black Hole Binary, V4641 Sgr
Makoto Uemura, Taichi Kato, Ryoko Ishioka +8
We report on unprecedented short-term variations detected in the optical flux from the black hole binary system, V4641 Sgr. Amplitudes of the optical fluctuations were larger at lo…
Recurrent Nova IM Normae
T. Kato, H. Yamaoka, W. Liller +1
We detected the second historical outburst of the 1920 nova IM Nor. Accurate astrometry of the outbursting object revealed the true quiescent counterpart having a magnitude of R=17…
