This core is not still, it is constantly moving and slowly spinning. When it collapses however, it begins to move faster and faster. As the core's movement and spinning accelerate, the natal envelope that surrounds and shields the protostar begins to flatten. and thus, a flattened disk forms around the protostar and it is within that disc that lanes will form.
Eventually, the gas in the core gets so hot, greater than 10,000,000 degrees. That's a lot of zeros! It gets so hot that the hydrogen atoms begin to fuse creating a firm and stable source of energy. and BOOM, a star is born!
However, don't get to excited, there are a number of problems associated with observing this process of a star formation. One of which is the fact that the process is just too long; forming stars and plants takes a very long time, up to billions of years. so, it's not quiet easy to pick out a particular region in space and watch it go throughout this process and captivate all the steps until it becomes a star. and so we rely on statistics and facts. When we take a picture in space, we can identify a region of active star formation that contains a good number of stars in their different stages of evolution. We can thus, by observing each different stage and each of these objects, begin to understand this long and difficult process of star birth and it's evolution.
Another problem is, just like humans, the earliest phases of stellar birth is hardly observable. In fact, the initial stages of human development. the fetes, is not directly observable. the earliest phases of stellar have a very similar problem. As we said, during the protosellar stage, the young fetal star is still surrounded and shield by it's natal envelope that contains clouds of gas and dust in which they are conceived. Luckily, just like humans, or doctors as opposed to astronomers, have eventually discovered and devoted techniques to see the fetes inside the mother, astronomers have discovered and devlopped many different techniques to actually see and obverse the fetal star, or the protostar within the cold, dense clouds in which they form. This technique that astronomers have discovered involves using infrared and redo radiation emitted by the protostar and the surrounding gas and dust in which it forms.
