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.
It may be either. Juvenile means young.
The Sun is a medium mass star in main sequence.
Yes.
Sirius B is a white dwarf. So it is low mass compared to other stellar remnants.
Orion is a constellation, not a star. Betelgeuse, the red giant at the left shoulder of Orion, is a supergiant.
High mass.

High mass.
The sun is an intermediate-mass star.
Low mass
No, it's low mass.
The life of a high mass star goes like this: A nebula gets hot and nuclear fusion binds it into a high-mass protostar the protostar ages into high-mass, very hot star that hot star explodes into a supergiant, which proceeds to explode into a supernova the supernova then shrinks into a neutron star or a black hole the life of a low- or medium-mass star goes like this: a nebula gets hot and nuclear fusion binds it into a low-mass protostar the protostar ages into a low- or medium- mass,cool star the star explodes into a red giant, the red giant explodes into a planetary nebula the nebula shrinks into a white dwarf, which then dims into a black dwarf i hope i was able to answer your question.
white dwarf
There are more low mass stars. this is for two reasons:- # the star forming process generates more low mass stars # High mass stars burn out very quickly and explode as supernovas and thus over time there are less and less of them.
It may be either. Juvenile means young.
The Sun is a medium mass star in main sequence.
