Observability of inflated companion stars after supernovae in massive binaries

We carry out a systematic study of the response companion stars in massive binaries after being impacted by supernova ejecta. A total 720 1D stellar evolution calculations are performed to follow inflation and contraction star energy injection how it depends on various parameters. find that maximum luminosity achieved during inflated phase is only dependent mass we derive an analytic formula describe relation. There also tight correlation between duration expansion intersected energy. These correlations will be useful constrain pre-supernova binary parameters from future detections companions. discuss possible outcomes system when taken into account. Based simple population synthesis, estimate $\sim$1-3% stripped-envelope supernovae may have observable Finally, apply our models observed SN2006jc place strong constraints
