Spectroscopic Observations of V455 Andromedae Superoutburst in 2007: the Most Exotic Spectral Features in Dwarf Nova Outbursts
Yusuke Tampo, Daisaku Nogami, Taichi Kato +10
We present our spectroscopic observations of V455 Andromedae during the 2007 superoutburst. Our observations cover this superoutburst from around the optical peak of the outburst t…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. X: The Tenth Year (2017)
Taichi Kato, Keisuke Isogai, Yasuyuki Wakamatsu +67
Continuing the project described by Kato et al. (2009, PASJ, 61, S395, arXiv/0905.1757), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly duri…
Third Nearest WZ Sge-Type Dwarf Nova candidate ASASSN-14dx Classified on the Basis of Gaia Data Release 2
Keisuke Isogai, Taichi Kato, Akira Imada +8
ASASSN-14dx showed an extraordinary outburst whose features are the small outburst amplitude (~ 2.3 mag) and long duration (> 4 years). Because we found a long observational gap of…
OAO/MITSuME Photometry of Dwarf Novae. III. CSS130418:174033+414756
Akira Imada, Keisuke Isogai, Kenshi Yanagisawa +1
We report on multicolour photometry of the short period dwarf nova CSS130418:174033+414756 during the 2013 superoutburst. The system showed an unusually short superhump period with…
On the Colour Variations of Negative Superhumps
Akira Imada, Kenshi Yanagisawa, Nobuyuki Kawai
We present simultaneous , , and photometry of the notable dwarf nova ER UMa during the 2011 season. Our photometry revealed that the brightness maxima of…
OAO/MITSuME Photometry of Dwarf Novae. II. HV Virginis and OT J012059.6+325545
Akira Imada, Keisuke Isogai, Takahiro Araki +3
We report on multicolor photometry of WZ Sge-type dwarf novae, HV Vir and OT J012059.6+325545 during superoutbursts. These systems show early superhumps with the mean periods of 0.…
