A New WZ Sagittae-type Dwarf Nova KSP-OT-202104a Near the Period Minimum from the KMTNet Supernova Program
Sang Chul Kim, Youngdae Lee, Dae-Sik Moon +4
We present photometric and spectroscopic studies of a new WZ Sagittae (Sge)-type dwarf nova (DN) KSP-OT-202104a discovered by the Korea Microlensing Telescope Network Supernova Pro…
K-DRIFT Science Theme: New Theoretical Framework Using the Galaxy Replacement Technique for LSB studies
Kyungwon Chun, Jihye Shin, Rory Smith +13
Low-surface-brightness (LSB) structures provide critical insights into the hierarchical formation of galaxies and galaxy clusters. The KASI Deep Rolling Imaging Fast Telescope (K-D…
Infant Core-collapse Supernovae with Circumstellar Interactions from KMTNet I: Luminous Transitional Case of KSP-SN-2022c
Nan Jiang, Dae-Sik Moon, Yuan Qi Ni +6
We present multi-band high-cadence observations of a Type II supernova (SN) KSP-SN-2022c from a star-forming galaxy at 0.041 from its infant to nebular phase. Ea…
Infant Type Ia Supernovae from the KMTNet I. Multi-Color Evolution and Populations
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +6
We conduct a systematic analysis of the early multi-band light curves and colors of 19 Type Ia Supernovae (SNe) from the Korea Microlensing Telescope Network SN Program, including…
