WebStars are born out of the gravitational collapse of cool, dense molecular clouds. As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores. These protostars rotate faster and increase in temperature as they condense, and are surrounded by a protoplanetary disk out of which planets may later form. WebA star forms from massive clouds of dust and gas in space, also known as a nebula. Nebulae are mostly composed of hydrogen. Protostar Main sequence star As the mass … WebThe changes that occur in a star over time and the final stage of its life depend on a star's size . Nuclear reactions at the centre (or core) of a star provides energy which makes it shine brightly. This stage is called the ' main sequence '. The exact lifetime of a star depends very much on its size. Very massive stars use up their fuel quickly. lite in the box shoes
