Photometric study of southern SU UMa-type dwarf novae and candidates -- III: NSV 10934, MM Sco, AB Nor, CAL 86
T. Kato, P. Nelson, C. Stockdale +6
We photometrically observed four southern dwarf novae in outburst (NSV 10934, MM Sco, AB Nor and CAL 86). NSV 10934 was confirmed to be an SU UMa-type dwarf nova with a mean superh…
Outburst and Post-Outburst Active Phase of the Black Hole X-ray Binary V4641 Sgr in 2002
M. Uemura, T. Kato, R. Ishioka +19
The black hole X-ray binary V4641 Sgr experienced an outburst in 2002 May which was detected at X-ray, optical, and radio wavelengths. The outburst lasted for only 6 days, but the…
V803 Centauri: Helium Dwarf Nova Mimicking a WZ Sge-Type Superoutburst
T. Kato, R. Stubbings, B. Monard +3
We observed long-term behavior of the helium dwarf nova V803 Cen, and clarified the existence of at least two distinct states (state with 77-d supercycles and standstill-like state…
Photometric study of new southern SU UMa-type dwarf novae - II: Authentication of BF Ara as a Normal SU UMa-type Dwarf Nova with the Shortest Supercycle
T. Kato, G. Bolt, P. Nelson +5
We photometrically observed the 2002 August long outburst of BF Ara. The observation for the first time unambiguously detected superhumps (average period 0.08797(1) d), qualifying…
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…
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…
