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…

Stellar Tidal Disruptions by Newborn Neutron Stars or Black Holes: A Mechanism for Hydrogen-poor (Super)luminous Supernovae and Fast Blue Optical Transients
Daichi Tsuna, Wenbin Lu
Hydrogen-poor supernovae (SNe) of Type Ibc are explosions of massive stars that lost their hydrogen envelopes, typically due to interactions with a binary companion. We consider th…
