Stellar Metamorphosis as Alternative to Nebular Hypothesis

According to the mainstream dogma solar systems have a central star which centralizes the majority of the material that forms the theorized disk surrounding it, therefore these stars should not be separate, but should have combined into a single larger star.

R136a1
RMC 136a1 (usually abbreviated to R136a1) is a Wolf-Rayet star located at the center of R136, the central condensation of stars of the large NGC 2070 open cluster in the Tarantula Nebula. It lies at a distance of about 50 kiloparsecs (163,000 light-years) in the Large Magellanic Cloud. It has the highest mass and luminosity of any known star, at 265 M☉ and 8.7 million L☉, and also one of the hottest at over 50,000 K.
