How do dying low mass stars create elements?

Supernovae can leave behind neutron stars, which may later merge to produce additional heavy elements. Dying low-mass stars throw off their enriched outer layers, leaving behind white dwarfs. The process of producing new elements is called nucleosynthesis.

How are low mass elements formed?

The low-mass elements, hydrogen and helium, were produced in the hot, dense conditions of the birth of the universe itself. The birth, life, and death of a star is described in terms of nuclear reactions. The chemical elements that make up the matter we observe throughout the universe were created in these reactions.

What element does a dying star produce?

Astronomers know certain elements form inside stars and then spew into space when dying stars explode. These are elements such as carbon, oxygen and iron. Scientists call these light elements as they have less mass than those such as gold and platinum.

What is the process of creating elements?

Heavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together. The simplest reactions involve hydrogen, whose nucleus consists only of a single proton, but other fusion reactions, involving mergers of heavier nuclei, are also possible.

How does the mass of a star determine its death?

The way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant.

How does mass influence how a star lives and dies?

Explanation: If the star has smaller mass than the Sun, it can fuse hydrogen into helium for atleast a trillion years. The larger a star, the shorter its life because it fuses hydrogen into helium much more quickly. A star whose mass is more than 20 Suns will run out of hydrogen in only a few hundred million years.

What elements are in low mass stars?

Low mass stars end up as White Dwarfs composed of mainly Carbon and Oxygen. Medium mass stars have higher temperatures in their cores. The higher T allows fusion reactions creating Oxygen, Neon, Sodium and Magnesium. Medium mass stars end up as White Dwarfs composed of the higher mass elements.

How do stars form elements?

When the new star reaches a certain size, a process called nuclear fusion ignites, generating the star’s vast energy. The fusion process forces hydrogen atoms together, transforming them into heavier elements such as helium, carbon and oxygen.

What is the last element formed before a star dies?

The star stops producing energy and dies, but in those final stages it sheds its outer layers. This material blows out into interstellar space, carrying with it traces of the heavier elements it once formed, primarily carbon.
