When our sun reaches the end of its lifetime, it will turn into a red giant. ![]() But the main-sequence lifetime of these very small stars is longer than the age of the universe, so this has never actually happened yet. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star.Ī red dwarf that is too small to become a red giant will not turn into a planetary nebula: its fusion processes will eventually cease and it will probably produce a white dwarf made mostly of helium. A massive star will undergo a supernova explosion. However, their life cycles start to differ after the red giant phase. What happens to a red giant after a supernova? For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. The illustration above compares the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. What happens to low mass stars after the red giant phase? At this stage, the star’s matter is extremely dense. Gravity causes the last of the star’s matter to collapse inward and compact. When the last of the helium atoms in the core are fused into carbon atoms, the medium size star begins to die. What is the final stage of a medium mass star? Stage 4 – The star begins to release energy, stopping it from contracting even more and causes it to shine. Stage 3 – At this temperature, nuclear reactions in which hydrogen fuses to form helium can start. A star forms from massive clouds of dust and gas in space, also known as a nebula. What are the stages of a star life cycle in order? They typically have a quick main sequence phase, a short red supergiant phase, and a spectacular death via a supernova explosion. What are the stages in the life cycle of a massive star?Īny star which is larger than eight solar masses during its regular main sequence lifetime is considered a massive star. The core remains as a white dwarf and eventually cools to become a black dwarf. A planetary nebula is formed by the outer layers. As the core collapses, the outer layers of the star are expelled. What is the final stage of a low mass star?įor low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. What are the 5 stages of the life cycle of a star? Then the star will slowly contract and cool to become a white dwarf: Earth-sized, ultra-dense star corpses radiating a tiny fraction of their original energy. Once at the red giant stage, a star might stay that way for up to a billion years. A star originates from a large cloud of gas. What are the 7 stages of a low mass star?Īll stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant. When hydrogen fusion can no longer happen in the core, gravity begins to collapse the core again. Low mass stars spend billions of years fusing hydrogen to helium in their cores via the proton-proton chain.
