In the last stage of stellar evolution following a supernova stars too massive to form neutron stars may form a?
In the last stage of stellar evolution, stars too massive to form neutron stars may collapse into black holes following a supernova explosion. When these massive stars exhaust their nuclear fuel, their cores collapse under gravity, leading to an event horizon that characterizes a black hole. The outer layers are expelled during the supernova, while the core's collapse results in an incredibly dense singularity from which nothing, not even light, can escape. This process marks the end of the star's life cycle, transitioning it into a black hole.
What effect do neutron stars and pulsars have on Earth?
Hardly any - they are very far away. However, a supernova (which would come before a neutron star) could have catastrophic effects on Earth, if it were to happen in our neighborhood (up to a few thousand light years!).
Why is there an upper limit to the mass of neutron stars?
There is an upper limit to the mass of neutron stars because if the neutron star is too massive, neutrons would be crushed by the gravity of the neutron star, and the neutron star would collapse into a black hole.
Why do some stars become black hole stars and not neuron stars?
Actually if a star is medium or low mass is will run out of fuel and turn into a red giant, once the stars atmosphere slowly drifts away and the core is remaining it will eventually become a white dwarf For more massive stars it will turn in to a super giant the will cause a supernova, after the supernova the star can either a black hole or a neutron star
Is a main -sequence star of a spectral type A diameter larger than Jupiter?
ANY star is more massive than Jupiter. However, I assume you refer to the diameter. Here, too, ANY star is larger than Jupiter - with the exception of dead stars (stars in which nuclear fusion has stopped, i.e., white dwarfs, neutron stars, black holes), and perhaps some brown dwarves.

Why do some stars end up as neutron stars?
Some stars end up as neutron stars because they exploded as a supernova and leaves a dense core behind. The strong gravity of the core compresses itself until protons and electrons are crushed into neutrons, this forms a neutron star. If the core is too massive, it would collapse into a black hole.

Where do neutron stars appear on the Hertzsprung-Russell diagram and what significance does their placement hold in understanding stellar evolution?
Neutron stars do not appear on the Hertzsprung-Russell diagram because they are not in the main sequence phase of stellar evolution. Neutron stars are the remnants of massive stars that have undergone supernova explosions. Their formation and properties are better understood through other astrophysical models and observations.
What cause a neutron star to form?
The strong gravity of the core of a dead high-mass star causes a neutron star to form. When the high-mass star becomes a supernova and leaves a core behind, the core no longer undergo fusion. Without fusion, gravity starts to push the core inward until most protons and electrons are crushed into neutrons, a neutron star forms. If the core is too massive, the neutron star would collapse and become a black hole.

How do the characteristics of really massive stars differ from stars with masses like the sun?
Massive stars, which are much larger than the sun, have shorter lifespans, burn hotter and brighter, and eventually explode in a supernova. They also have the potential to form black holes or neutron stars after their explosion.

What do collapsed stars form?
Collapsed stars form black holes, which have such a strong gravitational pull that not even light can escape. They can also form Neutron Stars, which are so dense that one grain of sand in the form of a neutron star could throw the earth off course. As well as nebulae, which are massive clouds of gas and dust.
Why do some pairs of neutron stars collide and merge?
Neutron stars can collide and merge due to their strong gravitational attraction towards each other. When two neutron stars are in close proximity, their orbits can decay over time, leading to a collision and eventual merger. This process releases a significant amount of energy in the form of gravitational waves and can result in the formation of a black hole or a more massive neutron star.
Where does a neutron star fall on the Hertzsprung-Russell diagram in relation to other stellar objects?
A neutron star falls on the Hertzsprung-Russell diagram in a different region compared to other stellar objects. Neutron stars are typically found in the lower left corner of the diagram, separate from main sequence stars and other types of stars.
