Probing the Nature of the Circumstellar Material Surrounding SN 2024ggi: A Search for Precursor Emission and Constraints from Radio Observations
Tobias Géron, James K. Leung, Maria R. Drout +8
We present an analysis of the pre-explosion optical light curve and post-explosion radio observations of the nearby supernova (SN) 2024ggi, a Type II SN discovered in NGC 3621 at a…
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…
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…
A cosmic formation site of silicon and sulphur revealed by a new type of supernova explosion
Steve Schulze, Avishay Gal-Yam, Luc Dessart +47
The cores of stars are the cosmic furnaces where light elements are fused into heavier nuclei. The fusion of hydrogen to helium initially powers all stars. The ashes of the fusion…
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…
Diagnosis of Circumstellar Matter Structure in Interaction-powered Supernovae with Hydrogen Line Feature
Ayako T. Ishii, Yuki Takei, Daichi Tsuna +2
Some supernovae (SNe) are powered by collision of the SN ejecta with a dense circumstellar matter (CSM). Their emission spectra show characteristic line shapes of combined broad em…
Simulating Hydrogen-poor Interaction-Powered Supernovae with CHIPS
Yuki Takei, Daichi Tsuna, Takatoshi Ko +1
We present the updated open-source code Complete History of Interaction-Powered Supernovae (CHIPS) that can be applied to modeling supernovae (SNe) arising from an interaction with…
Detached and Continuous Circumstellar Matter in Type Ibc Supernovae from Mass Eruption
Daichi Tsuna, Yuki Takei
Some hydrogen-poor supernovae (SNe) are found to undergo interaction with dense circumstellar matter (CSM) that may originate from mass eruption(s) just prior to core-collapse. We…
Precursors of Supernovae from Mass Eruption: Prospects for Early Warning of Nearby Core-collapse Supernovae
Daichi Tsuna, Yuki Takei, Toshikazu Shigeyama
Recent observations of a large fraction of Type II supernovae show traces of dense circumstellar medium (CSM) very close to the progenitor star. If this CSM is created by eruptive…
Eruption of the Envelope of Massive Stars by Energy Injection with Finite Duration
Takatoshi Ko, Daichi Tsuna, Yuki Takei +1
A significant fraction of supernovae show signatures of dense circumstellar material (CSM). While multiple scenarios for creating a dense CSM exist, mass eruption due to injection…
CHIPS: Complete History of Interaction-Powered Supernovae
Yuki Takei, Daichi Tsuna, Naoto Kuriyama +2
We present the public release of the Complete History of Interaction-Powered Supernovae (CHIPS) code, suited to model a variety of transients that arise from interaction with a den…
