What are the 2 types of stars that produce supernovae?
Red Giants and black holes
What do you call a star in a late stage of development?
Stars are expected to end up as white dwarves, neutron stars, or black holes. If you are interested in the stages before that (when the star still produces power), that include red giants, and supernovae.
What is a red giants core called?
A red giant's core is called a helium core. This is because as a red giant forms, the core of the star contracts and heats up, causing hydrogen fusion to transition to helium fusion.
How does a main sequence star get its energy?
Main sequence stars get their energy through nuclear fusion in their cores. This process involves the fusion of hydrogen atoms to form helium, releasing energy in the form of light and heat. The energy generated from nuclear fusion is what allows main sequence stars to balance the inward force of gravity with the outward pressure of the radiation created in the core.
Who is better giants or saints?
Giants by far
What are the 2 types of stars that produce supernovae?
Red Giants and black holes
What are the particles for the nuclear fusion in stars?
A variety of different fusion reactions are possible. In our sun, which is classified as medium sized, it is fusion of hydrogen nuclei, ie protons, to form helium. In larger stars, especially red giants, larger nuclei react in fusion, so that larger and heavier nuclei get formed.
How are red giants and blue giants similar?
Red giants and blue giants are both stages in the evolution of massive stars that have exhausted their hydrogen fuel. Despite their color differences, both types of stars expand and cool as they transition into later stages of their life cycles, resulting in significant changes in size and luminosity. They also share similar processes in terms of nuclear fusion, with red giants fusing helium and heavier elements, while blue giants primarily undergo hydrogen fusion at a much higher temperature. Ultimately, both contribute to the cosmic cycle of matter through supernovae and the creation of heavier elements.
Why does fusion continue in red supergiants?
Fusion continues in red supergiants because their cores are able to fuse heavier elements such as helium into even heavier elements like carbon, neon, and oxygen. The high temperatures and pressures in the core allow nuclear fusion reactions to continue, powering the star and maintaining its equilibrium.
What is the main source of energy for red giants?
the fusion of hydrogen in a shell outside the cor
Compare and contrast super giants and giant stars?
Super giants are more massive and have larger radii than giant stars. Super giants are in a more advanced stage of stellar evolution compared to giant stars. Both types of stars eventually exhaust their nuclear fuel and go on to evolve into other stages, such as supernovae or white dwarfs.
Name the four main types of stars?
The four types of stars are; Main Sequence, White Swarfs, Red Giants and Super Giants. 90% of stars are in the Main Sequence.
Why do stars not become red giants?
Most medium mass stars such as our Sun DO become red giants. Smaller stars do not have enough mass to initiate helium fusion when the hydrogen supply begins to run low, and do not become red giants.
What is the mass of a blue giant star?
Blue giant stars typically have masses ranging from about 10 to over 100 times that of our Sun. These stars are characterized by their high temperatures and luminosities, which result from their rapid rate of nuclear fusion. Due to their massive size, blue giants have relatively short lifespans, often only lasting a few million years before evolving into supernovae or other end-stage phenomena.
What do you call a star in a late stage of development?
Stars are expected to end up as white dwarves, neutron stars, or black holes. If you are interested in the stages before that (when the star still produces power), that include red giants, and supernovae.
What energy changes in a star?
In a star, energy changes primarily occur through nuclear fusion, where hydrogen nuclei fuse to form helium, releasing vast amounts of energy in the form of light and heat. This process generates the energy that powers the star and creates pressure to counteract gravitational collapse. As the star ages, it undergoes changes in fusion processes, eventually fusing heavier elements, which alters its energy output and leads to different stages of stellar evolution, such as red giants or supernovae. Ultimately, energy changes in a star reflect its life cycle and the transformations within its core.
What is a red giants core called?
A red giant's core is called a helium core. This is because as a red giant forms, the core of the star contracts and heats up, causing hydrogen fusion to transition to helium fusion.
