What are the small dense remains of a high mass star?
The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
Is low and high mass stars indirect or inverse?
Low and high mass stars are indirectly related; high mass stars evolve faster and have shorter lifespans compared to low mass stars. This is because high mass stars burn through their fuel at a faster rate due to their higher core temperature and pressure.
What are the small dense remains of a high-mass star called?
The small dense remains of a high-mass star are called neutron stars or black holes, depending on the mass of the star. Neutron stars are formed when the core collapses under its own gravity, while black holes are formed when the core collapses into a singularity.
What happens when a stars core runs out of oxygen?
Unless a star ts very old and very massive, it will not consume oxygen. Stars are powered by nuclear fusion, which fuses hydrogen into helium. When a star runs out of hydrogen at its core it expands into a red giant and starts fusing hydrogen in a shell around the core. If the star is not massive enough to fuse helium, then it will shed its outer layers and leave a helium while dwarf where the core was. If it is massive enough, it will fuse helium into heavier elements up to oxygen. Most stars to not make it past this stage. More massive stars, though fuse elements such as carbon and oxygen into neon, magnesium, and sulfur. If at any stage the star can fuse no more, the it sheds its outer layers and leaves behind a white dwarf. The exception is if the star makes it as far as fusing iron. If that happens the core will stop producing energy. The core will collapse into either a black hole or a neutron star and the rest of the star's mass will be blown away in a massive explosion called a supernova.
What causes the formation of neutron stars?
Neutron stars are formed when a massive star runs out of fuel and collapses under its own gravity during a supernova explosion. The core of the star collapses into a dense ball of neutrons, creating a neutron star.
What makes a high-mass stars core collapse?
the high mass star's core collapse because its gravity
What is different about a star from a planet?
Stars are bigger than planets until they finally collapse into dwarf stars. Stars are large enough to produce nuclear energy in their core, so they produce high amounts of heat and light.
What is the core collapse speed for a supernova?
The core collapse speed for a supernova can be up to 70,000 km/s, or about 23% of the speed of light. This rapid collapse leads to the core reaching high densities and temperatures, triggering the explosive release of energy that characterizes a supernova event.
What are the small dense remains of a high mass star?
The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
When is the core collapse phase at the end of the life of a massive star triggered?
The core collapse of a massive star comences as the core has finished fusing the rest of its fuel into iron, the last and heaviest element forged in high-mass stars. At this point the risidual energy put out by the fusing of elements is not worth the energy it takes to fuse them together. Since the fusion process is no longer being carried out, the thermal radiation that is being created by thermonuclear fusion in the core is no longer available and cannot continue to push outward in the opposite direction of the force of gravity, so the impending collapse is triggered then by the ultimate win-out of gravity against the star's internal forces.
How are stars formed, step by step, from the initial collapse of a cloud of gas and dust to the ignition of nuclear fusion in their cores?
Stars are formed through a series of steps starting with the gravitational collapse of a cloud of gas and dust. As the cloud collapses, it heats up and forms a protostar. The protostar continues to contract and heat up until the core reaches temperatures high enough for nuclear fusion to begin. Once nuclear fusion ignites in the core, the star is born and begins to shine brightly.
Will the core of a high mass star turn into a nutron star?
Yes, the core of a high mass star will collapse under immense gravitational pressure during a supernova explosion, forming a neutron star. Neutron stars are incredibly dense and composed primarily of neutrons, hence the name.
What force causes extremely high mass stars to turn into black holes instead of nuetron stars?
Black holes are formed by super massive stars when they collapse. Less massive stars will form neutron stars. Therefore, the original size and mass of the star will determine if a black hole will be created when the star collapses.
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, that's correct! Stars are born when gravity causes gas and dust in a molecular cloud to collapse under their own weight. This collapse creates high pressures and temperatures in the core of the forming star, eventually igniting nuclear fusion and creating a stable star.
What is the hardest thing in the universe and why is it considered as such?
The hardest thing in the universe is believed to be neutron stars. These incredibly dense stars are formed when massive stars collapse under their own gravity. Neutron stars have a core made of densely packed neutrons, which gives them an extremely high density and strong gravitational pull. Their intense pressure and gravity make them incredibly difficult to break or deform, earning them the reputation as the hardest objects in the universe.
Where do neutron stars form?
Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.
How is a protostar created?
Sometimes. If the total mass is high enough, and if the cloud of dust and gas collapse to reach a high enough density and pressure, nuclear fusion can begin in the core and it will become a star. If the total mass is not high enough, it may collapse into a "brown dwarf".
