An optical transient candidate of 2-second duration captured by wide-field video observations
Noriaki Arima, Mamoru Doi, Shigeyuki Sako +14
Recent time-domain surveys have revealed rapid transients that evolve on timescales of days, expanding the transient population into the short-duration regime. The tr…

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…
