Type Ib supernovae are bluer than Type Ic supernovae
Harim Jin, Selma E. de Mink, Sebastian Holzner +5
The study finds that Type Ib supernovae are systematically bluer at peak than Type Ic supernovae, suggesting intrinsic differences in progenitor stripping rather than host galaxy r…

Near-Infrared and Optical Observations of SN 2024rbc: The First Early Detection of CO and Dust in a Type Ib Supernova
Ryan Hwangbo, Jeonghee Rho, Aravind P. Ravi +16
We present optical and near-infrared (NIR) observations of the Type Ib supernova (SN) 2024rbc. Emission from the first CO overtone, resting on a dust continuum at m, w…

Binary stars take what they get: Evidence for Efficient Mass Transfer from Stripped Stars with Rapidly Rotating Companions
Thibault Lechien, Selma E. de Mink, Ruggero Valli +5
Binary stars and their interactions shape the formation of compact binaries, supernovae, and gravitational wave sources. The efficiency of mass transfer - the fraction of mass reta…
