It's not got an exact definition, but astronomers usually mean a star of about
8 times the mass of the Sun or higher.
A high mass protostar will eventually evolve into a massive star like a red supergiant, followed by a supernova explosion. After the supernova event, the remnants may form a neutron star or a black hole.
The Sun is a medium mass star in main sequence.
High, typically 10 to 70 times (or more) the mass of our own sun.
White dwarf stage. Its shrinks to a lot extent in this stage. Edit: A high mass star is usually one that becomes a supergiant then a supernova. Eventually this should leave either a neutron star or a black hole, depending on the mass of the star. The previous answer is for low mass stars.
Juvenile star is typically classified as a low mass star, as it is in the early stage of its life cycle. These stars have a mass similar to that of the Sun or less. They are characterized by their long lifespan and relatively stable nature.
High mass.
A high mass star will leave behind either a neutron star of a black hole.
High mass.
no the sun is a medium mass star.
It can't. A blue star is a high-mass star. A yellow star has a medium mass.
no the sun is a medium mass star.
A low mass star will become a white dwarf star, eventually this will cool to become a black dwarf. A high mass star (at least 8 times the mass of our Sun) will form a neutron star or a black hole, after a supernova event.
