Want this question answered?
I am not aware of any specific element "signaling" this. Towards the end of a stars life, however, relatively large amounts of heavier elements are produced.
It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.
True. Our Sun will eventually produce elements as heavy as iron.
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
Yes, oxygen can be found in the spectral lines of many stars. ---------------------------------------------------------------------------------------------------------------- Stars are nuclear fusion furnaces that take light elements (hydrogen) and build them up into heavier elements (eg carbon and oxygen). Thus older and second or third generation stars have this element in their makeup.
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.

These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
Most stars that are around today are made of old material from dead stars. Those old stars produced oxygen as a product once they started fusing helium and heavier elements. Some old stars are currently producing oxygen through nuclear fusion.
True

True. Our Sun will eventually produce elements as heavy as iron.
The two main elements in stars are Hydrogen and Helium. Stars start out as mostly Hydrogen and produce Helium. There are less amounts of heavier elements like Oxygen, Neon and Iron in stars

They were formed in supernovae.
Absolutely,Most stars consist of hydrogen at the beginning which is burned into helium and heavier elements like oxygen, carbon, and iron depending on the size of the star.
