Men de innehåller också spårmängder av andra element, inklusive:

* Iron (Fe)
* Silicon (Si)
* Magnesium (Mg)
* svavel (S)
* nickel (ni)
* kalcium (CA)
* natrium (na)
* Aluminum (Al)
The specific composition of a star depends on its mass, age, and location in the galaxy. For example, younger stars tend to have a higher proportion of heavier elements than older stars.
How do we know the composition of stars?
Scientists use spectroscopy to study the light emitted by stars. The light is split into its different wavelengths, creating a unique pattern of absorption lines. These lines correspond to specific elements, allowing us to identify the star's composition.
Obs: The elements found in stars are the same elements found on Earth and throughout the universe. Stars are essentially giant fusion furnaces that create heavier elements from lighter ones.
