Fates of Rotating Supergiants from Stellar Mergers and the Landscape of Transients upon Core-collapse
Daichi Tsuna, Jim Fuller, Wenbin Lu
We present a grid of rotating supergiant models from post-main sequence binary merger products, constructed by the MESA stellar evolution code. We focus on the evolution of these s…
Multi-Phase Shock Cooling Emission in Ultra-Stripped Supernovae
Annastasia Haynie, Samantha C. Wu, Anthony L. Piro +1
Ultra-stripped and Type Ibn supernovae (USSNe and SNe Ibn, respectively) are fast-evolving, hydrogen-poor transients that often show signs of interaction with dense circumstellar m…
Transients by Black Hole Formation from Red Supergiants: Impact of Dense Circumstellar Matter
Daichi Tsuna, Xiaoshan Huang, Jim Fuller +1
Failed supernovae (SNe), which are likely the main channel for forming stellar-mass black holes, are predicted to accompany mass ejections much weaker than typical core-collapse SN…
Merger Precursor: Year-long Transients Preceding Mergers of Low-mass Stripped Stars with Compact Objects
Daichi Tsuna, Samantha C. Wu, Jim Fuller +2
Binary mass transfer can occur at high rates due to rapid expansion of the donor's envelope. In the case where mass transfer is unstable, the binary can rapidly shrink its orbit an…
Bright Supernova Precursors by Outbursts from Massive Stars with Compact Object Companions
Daichi Tsuna, Tatsuya Matsumoto, Samantha C. Wu +1
A fraction of core-collapse supernovae (SNe) with signs of interaction with a dense circumstellar matter are preceded by bright precursor emission. While the precursors are likely…
