TCP J072226836220548: a new AM CVn type system with infrequent outbursts
Alexander Tarasenkov, Kirill Sokolovsky, Alexandr Dodin +11
We present the discovery of TCP J072226836220548, a new ultracompact binary system of the AM CVn type. This system was first identified displaying a mag outburst on 2…
Unravelling the asphericities in the explosion and multi-faceted circumstellar matter of SN 2023ixf
Avinash Singh, R. S. Teja, T. J. Moriya +33
We present a detailed investigation of photometric, spectroscopic, and polarimetric observations of the Type II SN 2023ixf. Earlier studies have provided compelling evidence for a…
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…
