Confined Circumstellar Material as a Dust Formation Site in Type II Supernovae
Yuki Takei, Kunihito Ioka, Masaru Shibata
We propose a model for dust formation in Type II supernovae (SNe) interacting with confined circumstellar material (CSM), motivated by recent time-domain surveys that have revealed…

Population Synthesis Study on the Binary Origin of Type Ibn Supernovae
Takatoshi Ko, Tomoya Kinugawa, Daichi Tsuna +2
Type Ibn supernovae (SNe) are a class of SN explosions whose progenitors are surrounded by dense helium-rich circumstellar matter (CSM). Some models have been proposed for how to f…

Detached Circumstellar Matter as an Explanation for Slowly-Rising Interacting Type Ibc Supernovae
Yuki Takei, Daichi Tsuna
Some hydrogen-poor (Type Ibc) supernovae (SNe) are known to have massive circumstellar matter (CSM) that are well detached from the star. Using the open-source code CHIPS, we const…
