Why mass is so important in determining the evolution of a star?
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.
What is the heaviest element that can be made by normal processes inside a star?
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.
What is a good opening sentence for a science paper on massive stars?

How does the intensity of a spectral line yield information about the source of the light?
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.
Why are massive stars called element factories?
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.

What is the heaviest smallest object?
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.
Which is the Element abundantly present in the universe especially in stars?
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.
In stars more massive than the Sun fusion continues until the core is almost all?
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.
Did iron form your solar system?
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.
What are the heaviest things?
neutron stars
Why is iron the heaviest element that can be produced in a star?
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.
What do the most massive stars end their life as?
The massive stars turn into gas
Do massive stars become neutron stars?
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.

How does the future of massive stars differ from the future of smaller stars?
Massive stars are most likely to explode faster than smaller stars.
