It sure can - and some stars do, to a minor degree. However, it can no longer gain energy from this fusion - it costs energy to create heavier elements.

To fuse Iron, you would need a huge amount of heat and pressure, higher than what can be provided by even the massive stars is existence. The upper limit of a stars mass puts this limit on what materials it can fuse. Elements heavier than Iron are created during a supernova explosion, the death of a massive star.
Helium. A low mass star does not have enough mass to generate the heat needed to fuse helium.
The heaviest element that can be produced prior to supernova is Iron (Fe).
The final core element for a massive star is iron. When a massive star exhausts its nuclear fuel, iron builds up in its core due to fusion reactions. Iron cannot undergo further fusion to release energy, leading to a collapse and subsequent supernova explosion.
Well friend, after a star goes supernova, the last element that forms in its core is usually iron, a true star of the show! As the star expands and contracts in its final moments, different elements fuse together until only iron remains. It's all part of nature's beautiful dance, showing us the wonder and complexity of the universe.
Spectral lines of an element in a star's spectrum may be weak despite the element being abundant due to several factors. One reason could be the temperature of the star, which may not be conducive to exciting the atoms of that element to the necessary energy levels for strong absorption. Additionally, if the element is in a highly ionized state due to the star's extreme temperatures, it may not effectively absorb light at the wavelengths corresponding to its spectral lines. Lastly, turbulence or Doppler broadening in the star's atmosphere can also contribute to the weakening of the spectral lines.
Helium.

They analyze the star's spectrum. Each element produces characteristic lines in a spectrum.
The first element that is converted in a star's core is hydrogen. Through nuclear fusion, hydrogen atoms fuse together to form helium, releasing energy in the process. This fusion process is what powers a star and allows it to shine.
The heaviest element that can be produced prior to supernova is Iron (Fe).
Iron fusion cannot support a star because iron is the most stable element and cannot release energy through fusion reactions. This causes the star to collapse, leading to a supernova explosion.

The final core element for a massive star is iron. When a massive star exhausts its nuclear fuel, iron builds up in its core due to fusion reactions. Iron cannot undergo further fusion to release energy, leading to a collapse and subsequent supernova explosion.
Stars cannot fuse iron because it requires more energy than it produces, causing the star to lose its balance between gravity and radiation pressure. This imbalance leads to the star's collapse and eventual supernova explosion.
The main fuel for a red giant star is hydrogen, which is fused into helium in the star's core during the earlier stages of its life. As the hydrogen in the core gets depleted, the star begins to fuse helium and other heavier elements in shells surrounding the core. This process causes the star to expand and cool, giving it the characteristic red color. Eventually, red giants may go on to fuse heavier elements as they evolve further.
A dual element fuse provides better protection for equipment by being able to handle the temporary high inrush currents that can occur during normal operation. This type of fuse also has a faster response time to protect against overloads and short circuits, making it more reliable for sensitive equipment.
