The Near-Infrared Echo from SN 2023xgo: Evidence for a Massive Pre-Supernova Eruption in a Type Ibn/Icn Supernova
Masayuki Yamanaka, Takahiro Nagayama
We present near-infrared (NIR) and optical observations and analysis of the Type Ibn/Icn supernova (SN) 2023xgo, spanning the period from two days to 100 days past explosion. A com…
SN 2023vbg: A Type IIn Supernova Resembling SN 2009ip, with a Long-Duration Precursor and Early-Time Bump
Sota Goto, Masayuki Yamanaka, Takahiro Nagayama +9
Type IIn supernovae (SNe) resembling SN 2009ip (09ip-like SNe) originate from the interaction between circumstellar material (CSM) and the ejecta. This subclass not only shares sim…
SN 2024iss: Double-Peaked Light Curves and Implications for a Yellow Supergiant Progenitor
Masayuki Yamanaka, Takahiro Nagayama, Tsukiha Horikiri
We report the multi-band photometric observations of the Type IIb supernova (SN) 2024iss with ultra-violet (UV), optical, and near-infrared (NIR) wavelengths starting one day after…
