A cool and inflated progenitor candidate for the Type Ib supernova 2019yvr at 2.6 yr before explosion
ABSTRACT We present Hubble Space Telescope imaging of a pre-explosion counterpart to
SN 2019yvr obtained 2.6 yr before its explosion as a type Ib supernova (SN Ib). Aligning to a …

Investigating the properties of stripped-envelope supernovae; what are the implications for their progenitors?
We present observations and analysis of 18 stripped-envelope supernovae observed during
2013–2018. This sample consists of five H/He-rich SNe, six H-poor/He-rich SNe, three …

A 12.4-day periodicity in a close binary system after a supernova
Neutron stars and stellar-mass black holes are the remnants of massive star explosions.
Most massive stars reside in close binary systems, and the interplay between the companion …

Binary-stripped stars as core-collapse supernovae progenitors
Most massive stars experience binary interactions in their lifetimes that can alter both the
surface and core structure of the stripped star with significant effects on their ultimate fate as …
