WebTheories surrounding this cocoon formation fall into two categories (opens in new tab) based on how rapidly red supergiants accrete this material. The ‘superwind’ scenario suggests that the pre-explosion cocoon is formed as a result of a steady flow of material from the red supergiant for a period of up to 100 years prior to a supernova explosion. WebStephenson 2 DFK 1 (abbreviated to RSGC2-01), also known as Stephenson 2-18 (abbreviated to St2-18), is an enigmatic red supergiant (RSG) or possible extreme red hypergiant (RHG) star in the constellation of Scutum.It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from …
