WebJust before its final gravitational collapse, the core of a massive star resembles an onion. The iron core is surrounded by layers of silicon and sulfur, oxygen, neon, carbon mixed with some oxygen, helium, and finally hydrogen. Outside the core, the composition is mainly hydrogen and helium. WebApr 13, 2024 · This leads credence to the "core accretion" model of star formation. In this model, the most massive stars collapse from single units of gas clouds and start their lives already with incredibly high masses. The observations support this idea because for the first time we have been able to observe a giant cloud of gas undergoing direct collapse ...
