We investigate the possible effects of the supernova (SN) ejecta hitting the companion star in iPTF 13bvn, focusing on the observable features when it becomes visible. iPTF 13bvn is a type Ib SN that may become the first case in which its progenitor is identified as a binary (by observations in the near future). According to calculations by Bersten et al. the progenitor should have a mass to reproduce the SN light curve, and such compact stars can only be produced via binary evolution. This is…

Disappearance of the Progenitor of Supernova iPTF13bvn
Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor candidate in pre-explosion images. We performed deep ultraviolet (UV) and optical
Comprehensive Study of Ejecta-companion Interaction for Core-collapse Supernovae in Massive Binaries
We carry out a comprehensive study of supernova ejecta-companion interaction in massive binary systems. We aim to physically understand the kinematics of the interaction and predict observational
The interaction of core-collapse supernova ejecta with a companion star
Context. The progenitors of many core-collapse supernovae (CCSNe) are expected to be in binary systems. After the SN explosion in a binary, the companion star may suffer from mass stripping and be
Observability of inflated companion stars after supernovae in massive binaries
We carry out a systematic study of the response of companion stars in massive binaries after being impacted by supernova ejecta. A total of 720 1D stellar evolution calculations are performed to
Origins of Type Ibn SNe 2006jc/2015G in interacting binaries and implications for pre-SN eruptions
Type Ibn supernovae (SNe Ibn) are intriguing stellar explosions whose spectra exhibit narrow helium lines with little hydrogen. They trace the presence of circumstellar material (CSM) formed via
Observational Properties of Type Ib/c Supernova Progenitors in Binary Systems
In several recent observational studies of Type Ib/c supernovae (SNe Ib/c), the inferred ejecta masses have a peak value of 2.0–4.0 , in favor of the binary scenario for their progenitors rather than
The origin of the possible massive black hole in the progenitor system of iPTF13bvn
This letter complements a formation scenario of the progenitor of the supernova iPTF13bvn proposed in Hirai (2017). Although the scenario was successful in reproducing various observational features
Formation scenario of the progenitor of iPTF13bvn revisited
The formation scenario of the progenitor of iPTF13bvn has been revisited. iPTF13bvn is unique in the sense that a corresponding pre-supernova image has been identified. This has enabled us to
Population Synthesis of Neutron Star X-Ray Binaries Associated with Supernova Remnants
Neutron star X-ray binaries (NS XRBs) associated with supernova remnants (SNRs) are youngest X-ray binaries that can provide insights into the early evolution of X-ray binaries and formation
The nature of the companion star in Circinus X-1
We present optical spectra and images of the X-ray binary Circinus X-1. The optical light curve of Cir X-1 is strongly variable, changing in brightness by 1.2 magnitudes in the space of four days.
