The emission spectrum of each element has characteristic lines for each element. Analyzing the spectrum of a star, you can figure out what elements are present, and also get an estimate on how much there is of each element. For more information, check the Wikipedia article on "emission spectrum".

What is the factories of elements?
If the question is where are elements made, the answer is in stars.
Can gas giants orbit closely to the stars they orbit?
Yes. We have detected gas giants orbiting very close to their stars.
What elements have been detected in a class B star?
helium and hydrogen
Why do scientists believe that stars contain the same elements as the solar system?
Scientists believe that stars contain the same elements as the solar system because all elements in the universe are created through nuclear fusion in the cores of stars. Elements are dispersed into space when stars explode as supernovae. These elements then form new stars, planets, and other celestial bodies, resulting in the similarities in elemental composition between stars and our solar system.
Why is hydrogen and helium found in all stars?
These elements are found in are very important in each of the five stars. all five stars because the elements
What did these first generation stars make?
First stars made the smallest elements, from hydrogen up and progressively larger stars made progressively larger elements
What two elements are the most common stars?
The two most common elements in the Universe, and in most stars are - in that order - hydrogen and helium (elements #1 and #2).
Why do younger stars have more heavy elements?
Younger stars have more heavy elements because they form from the remnants of older stars that have already produced and dispersed these elements through processes like supernova explosions.
Do stars form new elements?
Yes - in fact, most of the elements ONLY exist because they were formed in stars.
What is formed from stars?
All elements up to Iron are produced by smaller stars. heavier elements (everything heavier then iron) are produced from larger stars when they go supernova.
What is stars form?
All elements up to Iron are produced by smaller stars. heavier elements (everything heavier then iron) are produced from larger stars when they go supernova.
Are the sun moon and stars elements?
No
