What Is The Composition Of A Protostar? The gas is mostly made up of atoms of hydrogen, though small amounts of heavier elements can be found floating through space, as well. In some places, the interstellar medium is collected into a big cloud of dust and gas called a nebula. How a protostar is formed?
What Occurs During The Protostar Stage Of Star Formation? During the time a dense core is contracting to become a true star, but before the fusion of protons to produce helium begins, we call the object a protostar. Figure 7: Formation of a Star. (a) Dense cores form within a molecular cloud. What is the
Why Do Protostars Eventually Stop Their Gravitational Collapse? (3) A protostar stops collapsing when nuclear fusion begins in its center. … The center of the protostar, which is becoming hotter and denser with time, eventually reaches the point where it is so hot and so dense, hydrogen nuclei start to fuse together to form helium
What Happens When A Main Sequence Star Exhausts Its Core Hydrogen Fuel Supply? (1) When a star exhausts the hydrogen in its core, it becomes a giant or supergiant. Once a star has used up all the hydrogen in its core, fusion of hydrogen into helium stops. The core starts to contract again (just as
Do All Protostars Become Stars? Do all protostars become stars? Do all protostars become stars? Why or why not? No because not all stars have enough mass. Why don t all protostars become stars? These stars blow themselves apart and do not exist for long if at all. A protostar with less than 0.08 solar
