What are the 3 corpses of stars?
The three corpses of stars are white dwarfs, neutron stars, and black holes. White dwarfs are remnants of low to medium-mass stars that have shed their outer layers, leaving behind a hot core. Neutron stars form from the collapse of massive stars in supernova explosions and are incredibly dense, composed mostly of neutrons. Black holes result from the gravitational collapse of very massive stars, creating regions in space with gravity so strong that not even light can escape.
What event may trigger new star formation in a spiral arm?
If an interstellar cloud is massive enough that the gas pressure is insufficient to support it, the cloud will undergo gravitational collapse. The mass above which a cloud will undergo such collapse is called the Jeans mass. The Jeans mass depends on the temperature and density of the cloud, but is typically thousands to tens of thousands of solar masses. In so-called triggered star formation, one of several events might occur to compress a molecular cloud and initiate its gravitational collapse. Molecular clouds may collide with each other, or a nearby supernova explosion can be a trigger, sending shocked matter into the cloud at very high speeds. Finally, galactic collisions can trigger massive starbursts of star formation as the gas clouds in each galaxy are compressed and agitated by tidal forces.
If two objects have an equal mass does a more dense object have a greater gravitational pull?
No. The gravitational force exerted by one massive object on others depends only on its mass. So long as you are outside of the object, its density is irrelevant.
How does astronauts go into space when there is gravity?
The massive speed and acceleration of the spaceship is so great, that they are able to escape Earth's gravitational pull. Then at around the correct altitute, they can orbit the Earth safely.
What is a massive gravitationally bound?
A massive gravitationally bound system typically refers to a structure in the universe where a significant amount of mass, such as galaxies or galaxy clusters, is held together by gravitational forces. This binding occurs when the gravitational attraction between the constituent objects is strong enough to overcome their kinetic energy, preventing them from drifting apart. Such systems can include galaxies, star clusters, or even larger structures like superclusters, which play a crucial role in the large-scale structure of the universe.
How are black holes created in the universe?
By the gravitational collapse of massive stars - once they stop producing energy.
How are a black holes started?
It is believed that they usually start from the gravitational collapse of a massive star - once it runs out of fuel.
How the black hole make?
A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
Interstellar gas clouds may collapse to form stars if they?
if they are massive enough and have sufficient gravitational force to overcome pressure forces and begin the process of nuclear fusion, which powers stars. This collapse is triggered by disturbances such as shock waves from supernovae or gravitational interactions with other clouds.
What happens when a black hole collapses, and what are the consequences of this process?
When a black hole collapses, it shrinks in size and its gravitational pull becomes stronger. This process is called gravitational collapse. The consequences of this collapse include the black hole becoming denser and more massive, leading to an increase in its gravitational force. This can result in the black hole consuming nearby matter and energy, and potentially emitting powerful radiation and jets of particles.
Where did a singularty come from?
A singularity arises from an object that has mass, but zero volume, ie. a black hole. These come from stars that are too massive to simply explode, they collapse under their own gravitational force.
Do blue stars become black holes?
Yes, massive blue stars can eventually collapse and form black holes at the end of their lives. When a blue star exhausts its nuclear fuel, it undergoes a supernova explosion and if the remaining core is massive enough, it can collapse into a black hole due to gravitational forces.
What are the release dates for Massive Moves - 2010 Cliff Collapse 3-5?
Massive Moves - 2010 Cliff Collapse 3-5 was released on: USA: 20 January 2013
Will more massive objects attract each other with a greater gravitational force or a smaller gravitational force?
The more massive the objects, the greater the gravitational force between them. The gravitational force is affected by mass and distance. The closer two bodies are, the greater the gravitational force also.
What forms when the leftovers of a supernova are so massive that they collapse to form a dense object whose gravity is so strong that light cannot escape?
A black hole forms when the remnants of a supernova collapse under their own gravity, becoming so dense that not even light can escape its gravitational pull. This creates a region of spacetime exhibiting extreme gravitational effects from which nothing, not even light, can escape.
The space surrounding a massive object subject to the body's force of attraction is?
The space surrounding a massive object subject to the body's force of attraction is the gravitational field. This field is responsible for exerting a force on any other object within its influence, causing it to experience gravitational acceleration towards the massive object.
Where do pulsars originate from?
The collapse of massive stars - the same as neutron stars.
