a star will spend most of its life as a

On the left the star is seen as a protostar, embedded within a dusty disc of material as it forms. False. The more massive stars can fuse carbon into even heavier elements, which is where most of the heavy elements in the universe are made. By continuing to use this site you consent to the use of cookies on your device as described in our … Whether it was a "massive" star (some 5 or more times the mass of our Sun) or whether it was a "low or medium mass" star (about 0.4 to 3.4 times the mass of our Sun), the next … All stars spend most of their lives in this phase. The more massive a star is, the longer it lives because it has more hydrogen to fuse into helium. We use cookies to give you the best possible experience on our website. On the main sequence. High-mass star. What happens next in the life of a star depends on its initial mass. Convection in the outer layers of a star like the Sun helps mixing and makes more hydrogen available for burning. This is also the longest phase of a star's life. Eventually the core of the star runs out of hydrogen. Stars spend the majority of their lives fusing hydrogen, and when the hydrogen fuel is gone, stars fuse helium into carbon. A star will spend 90% of its life in the main sequence. After spending the majority of its life in this stage, the star's core begins to gradually heat up, the star expands and becomes redder until it transforms into a … Main sequence star. The main sequence is a line of stars plotted on the HR-diagram, which represent stars which are burning hydrogen, fusing it into helium. as a main sequence star. Term. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole. The fusion process in the core releases heat and light, supporting the star against further gravitational collapse, and making it shine. When a star leaves the main sequence stage, it will can go supernova and become a black hole or a neutron star. Before turning into a white dwarf, a star like the Sun will spend most of its life as a main sequence star. Our sun is currently a main sequence star. At this stage, existence will not be over just yet as it will continue to glow/exist for a lot longer than it was in the main sequence. True. It later becomes a star like our Sun. Our sun will spend about 10 billion years on the main sequence. More massive stars burn their fuel more quickly than less massive stars. Where on an H-R diagram does a star spend most of its life? However, a more massive star uses its fuel faster, and may only be on the main sequence for millions of years. The order of evolutionary stages of a star like the Sun would … The core contracts. When a star inward gravity and outward pressure are balanced the star is said to be in hydrostatic motion... A star will spend most of its life. Stars that are in the stable part of their life cycle are known as main sequence stars. A star will spend most of its shining lifetime in ... Our sun, along with most stars in the neighborhood probably formed about ... A star spends most of its life: Definition. When a Low mass star first run short of hydrogen and its core it becomes brighter because. Red Giant: Over the course of its life, a star is converting hydrogen into helium at its core. Answer - Answered by a verified Tutor. Stars spend most of their life in one spot on the main sequence. Yes Star spend most of their life span as a main sequence star. The largest stars have the shortest lives, and can last a few billion, and even just a few million years. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the age of the universe.The table shows the lifetimes of stars as a function of their masses. When that happens, the star can no longer hold up against gravity. Stellar evolution is the process by which a star changes over the course of time.
