Observational study of the extremely slow nova V1280 Scorpii
H. Naito, S. Mizoguchi, A. Arai +10
We present multi-color light curves and optical spectra of V1280 Scorpii obtained from 2007 to 2012. It is shown that V1280 Sco is the extremely slow nova and the mass of white dwa…
Precessing Warped Be Disk Triggering the Giant Outbursts in 2009 and 2011 in A 0535+262/V725 Tau
Yuki Moritani, Daisaku Nogami, Atsuo T. Okazaki +8
We carried out optical high-dispersion spectroscopic monitoring of the Be disk in a Be/X-ray binary A 0535+262/V725 Tau from 2009 to 2012, covering two giant outbursts and several…
Five-Year Optical and Near Infrared Observations of the Extremely Slow Nova V1280 Scorpii
H. Naito, S. Mizoguchi, A. Arai +10
We present optical (, , , and ) and near infrared (, and ) photometric and spectroscopic observations of a classical nova V1280 Sc…
Discovery of Multiple High-Velocity Narrow Circumstellar Na I D Lines in Nova V1280 Sco
Kozo Sadakane, Akito Tajitsu, Sahori Mizoguchi +2
We discovered multiple high-velocity (ranging from -900 to -650 km/s) and narrow (FWHM = 15 km/s) absorption components corresponding to both the D2 and the D1 lines of Na I on a h…
Photometric and Spectroscopic Observations of V1280 Sco
Hiroyuki Naito, Sahori Mizoguchi, Akira Arai +4
Photometries of B, V, Rc, Ic, y, J, and Ks bands and low dispersion optical spectroscopic observations of Nova V1280 Sco, started soon after the outburst, are reported. We show tha…
Optical light curves of RS Oph (2006) and hydrogen burning turnoff
Izumi Hachisu, Mariko Kato, Seiichiro Kiyota +11
We report a coordinated multi-band photometry of the RS Oph 2006 outburst and highlight the emission line free y-band photometry that shows a mid-plateau phase at y ~ 10.2 mag from…
