It may be either. Juvenile means young.
The Sun is a medium mass star in main sequence.
Yes.
High, typically 10 to 70 times (or more) the mass of our own sun.
Sirius B is a white dwarf. So it is low mass compared to other stellar remnants.
It depends on the density. Low density = dwarf Medium density = neutron star High density = black hole
High mass.
High mass.
The sun is an intermediate-mass star.
Low mass
No, it's low mass.
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.
The Sun is a medium mass star in main sequence.
Yes.
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.
High, typically 10 to 70 times (or more) the mass of our own sun.
In a newly formed star cluster stars with low masses must greaty out number stars with high masses. High mass stars are rare and low mass stars are extremely common.
