Iron is the heaviest element made in the bowels of any star with the exception of a supernova explosion. All natural elements heavier than iron come from one of those.
Hydrogen, helium, and carbon fuel are found in more massive stars. The diameter of more massive stars is bigger. Helium is found in greater abundance in more massive stars. The weight of more massive stars is greater.
Iron is the heaviest element that can be produced by normal processes inside a star through nuclear fusion. Elements heavier than iron are typically formed in supernova explosions or through other stellar processes.

The intensity of a spectral line can provide information about the abundance of the element or molecule that produced the line. Higher intensities indicate higher abundance, while lower intensities suggest lower abundance. This information can be used to study the composition and physical conditions of the source of light, such as stars or galaxies.
Prof. Brian Cox provides a great explanation in episode 2 of his excellent TV series 'Wonders of The Universe'. In short, many elements can only be created in the extreme conditions which exist within stars as they burn all their internal fuel and gradually 'die'. As they die, massive changes take place within stars, creating the conditions which are required to create different types of elements.

The heaviest smallest object is a neutron star. Neutron stars are incredibly dense remnants of massive stars that have collapsed under their own gravity, packing the mass of about 1.4 times that of the Sun into a sphere with a diameter of only about 12 miles.
Hydrogen is the most abundant element in the universe, making up 75% of ...Thiselement is found in great abundance in stars and gas giant planets.
Iron. Iron is the heaviest element that can be produced through nuclear fusion in a star, and once the core of a massive star is mostly composed of iron, it can no longer sustain fusion reactions. This triggers its collapse and ultimately leads to a supernova explosion.
Yes, iron is thought to have formed in the solar system through nuclear fusion processes in the cores of massive stars before being scattered into space through supernova explosions and later incorporated into the formation of our solar system.
neutron stars
Iron is the heaviest element that can be produced through nuclear fusion in stars because it has the most stable nucleus, with the lowest binding energy per nucleon. During fusion, lighter elements combine to form heavier ones, releasing energy, but once iron is formed, fusion no longer releases energy; instead, it requires energy. Therefore, in the cores of massive stars, fusion processes cease at iron, leading to the eventual collapse and supernova, where heavier elements are formed through different processes, such as neutron capture.
The massive stars turn into gas
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.

Massive stars are most likely to explode faster than smaller stars.
