Infant Core-collapse Supernovae with Circumstellar Interactions from KMTNet. I. Luminous Transitional Case of KSP-SN-2022c

Infant Core-collapse Supernovae with Circumstellar Interactions from KMTNet. I. Luminous Transitional Case of KSP-SN-2022c

We present BVi multiband high-cadence observations of a Type II supernova (SN) KSP-SN-2022c from a star-forming galaxy at z ≃ 0.041 from its infant to nebular phase. Early light-curve fitting with a single power law is consistent with the first detection roughly 15 minutes after shock breakout (SBO)...
