Abstract
Context . Type Ibn supernovae (SNe) are characterized by narrow helium (He I ) lines from photons produced by the unshocked circumstellar material (CSM). About 80 SNe Ibn have been discovered to date and only a handful of them have extensive observational records. Thus, many open questions remain regarding the progenitor system and the origin of CSM. Aims . Here, we investigate potential correlations between the spectral features of the prominent He I λ 5876 Å line and the optical and X-ray ligh..
