ABSTRACT
Some observations suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as supernovae, as do several models. Establishing a causal connection between these mass-loss episodes and the final explosion would provide a novel way to study pre-supernova massive-star evolution. Here we report observations of a mass-loss event detected 40?days before the explosion of the type?IIn supernova SN?2010mc (also known as PTF?10tel). Our photometric and spectroscopic data suggest that this event is a result of an energetic outburst, radiating at least 6?×?1047?erg of energy and releasing about 10?2 solar masses of material at typical velocities of 2,000?km?s?1. The temporal proximity of the mass-loss outburst and the supernova explosion implies a causal connection between them. Moreover, we find that the outburst luminosity and velocity are consistent with the predictions of the wave-driven pulsation model, and disfavour alternative suggestions.
