Elements heavier than oxygen, like the elements in the Periodic Table from iron to uranium, are produced during supernova explosions. These explosions occur when massive stars reach the end of their life cycle and undergo a catastrophic collapse. The extreme conditions present during a supernova allow for the fusion of lighter elements to form heavier elements through processes like rapid neutron capture (r-process) and slow neutron capture (s-process) nucleosynthesis. This is how elements heavier than oxygen are synthesized in the universe.
Elements heavier than oxygen are not produced in stars like the sun through normal stellar fusion processes because the temperatures and pressures in these stars are not high enough to facilitate the fusion of heavier elements. Supernovae, which are much more massive and energetic events than normal stars, are responsible for the production of elements heavier than oxygen through processes like rapid neutron capture (r-process) and slow neutron capture (s-process).
Heavier elements like carbon, oxygen, and iron were formed in the cores of stars through nuclear fusion processes. When massive stars exhaust their fuel, they go supernova, releasing heavy elements into space. These elements then become part of new stars and planets, including Earth.
The elements carbon, oxygen, and iron were formed in the interiors of stars that have since dies and exploded, spreading their contents through dust clouds that later formed other stars and solar systems.
The Sun can only produce elements up to carbon and oxygen through nuclear fusion in its core. For elements heavier than carbon and oxygen, higher temperatures and pressures are required, which can only be achieved in more massive stars or during supernova explosions.
Stars are primarily made up of hydrogen and helium, with small amounts of heavier elements such as carbon, oxygen, and iron. These elements are produced through nuclear fusion in the cores of stars. When a star reaches the end of its life and explodes in a supernova, these elements are scattered into space and can form new stars, planets, and other celestial bodies.

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.

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.
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
In cool stars, elements such as hydrogen and helium are primarily produced through nuclear fusion in their cores. Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.
True
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.
