A long-lasting eruption heralds SN 2023ldh, a clone of SN 2009ip
A. Pastorello, A. Reguitti, L. Tartaglia +46
We discuss the results of the spectroscopic and photometric monitoring of the type IIn supernova (SN) 2023ldh. Survey archive data show that the SN progenitor experienced some erra…
MASTER OT J030227.28+191754.5: an unprecedentedly energetic dwarf nova outburst
Yusuke Tampo, Taichi Kato, Keisuke Isogai +60
We present a detailed study of the MASTER OT J030227.28+191754.5 outburst in 2021-2022, reaching an amplitude of 10.2 mag and a duration of 60 d. The detections of (1) the double-p…
Optical and soft X-ray light-curve analysis during the 2022 eruption of U Scorpii: structural changes in the accretion disk
Katsuki Muraoka, Naoto Kojiguchi, Junpei Ito +52
We present our optical photometric observations of the 2022 eruption of the recurrent nova U Scorpii (U Sco) using 49,152 data points over 70 d following the optical peak. We have…
A remarkable recurrent nova in M31: Discovery and optical/UV observations of the predicted 2014 eruption
M. J. Darnley, M. Henze, I. A. Steele +20
The Andromeda Galaxy recurrent nova M31N 2008-12a had been caught in eruption eight times. The inter-eruption period of M31N 2008-12a is ~1 year, making it the most rapidly recurri…
The Hydrogen Burning Turn-off of RS Ophiuchi 2006
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…
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…
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…
Discovery of a Dwarf Nova Breaking the Standard Sequence of Compact Binary Evolution
M. Uemura, T. Kato, R. Ishioka +1
We revealed that the dwarf nova 1RXS J232953.9+062814 is an SU UMa-type system with a superhump period of 66.774+/-0.010 min. The short period strongly indicates that the orbital p…
