V463 Scuti (Nova Sct 2000): Rapidly Evolving Nova with a Prominent Premaximum Halt
T. Kato, M. Uemura, K. Haseda +3
We summarize photometric and spectroscopic observations of V463 Sct (Nova Sct 2000), which was originally thought to be a red variable. The spectrum taken on 2000 March 16.81 UT sh…
Deep Transient Optical Fading in the WC9 Star WR 106
T. Kato, K. Haseda, K. Takamizawa +1
We discovered that the WR9-type star WR 106 (HDE 313643) underwent a deep episodic fading in 2000. The depth of the fading (dV ~ 2.9 mag) surpassed those of all known similar "ecli…
Discovery of Extremely Large-Amplitude Quasi-Periodic Photometric Variability in WC9-Type Wolf-Rayet Binary, WR 104
T. Kato, K. Haseda, H. Yamaoka +1
We discovered that the Wolf-Rayet (WR)+OB star binary, WR 104, renowned for its associated "dusty pinwheel nebula" recently spatially resolved with infrared interferometry, exhibit…
Outburst of Possible Eclipsing Symbiotic Variable AS 289
Kesao Takamizawa, Minoru Wakuda, Taichi Kato
We discovered major brightenings of the symbiotic variable AS 289 in 1984 and 1995. During the outburst phase in 1996, we detected a temporary drop of the brightness. We consider t…
Remarkable yellow supergiant variable TmzV429
Taichi Kato, Kesao Takamizawa
We discovered that GSC 6554.559 is a previously unknown variable star, and named as TmzV429. We noticed that TmzV429 is identified with the IRAS-selected proto-planetary nebula (PP…
Discovery and Photometric Observation of the Optical Counterpart in a Possible Galactic Halo X-ray Transient, XTE J1118+480
M. Uemura, T. Kato, K. Matsumoto +7
We discovered the optical counterpart about 13 mag of a soft X-ray transient, XTE J1118+480 on 2000 March 30. We perform astrometry and provide the accurate position as R.A. = 11h1…
