The majority of hydrogen-rich Supernovae is covered in thick clouds of circumstellar material

A survey of the early lightcurves of hydrogen-rich Supernovae (type II SNe) and the analysis of their shapes revealed that the majority of SN progenitors shed vast amounts of material into their surroundings just before they die. This surprising result has been published by a large international team including scientists from the Argelander Institute for Astronomy.
