The largest and oldest stars are called Red Giants, although, some very small and incredibly massive stars, called Neutron stars, do exist. One tea spoon of Neutron star mater would weigh over 50 tonnes!
High mass.
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.
Altair is classified as an A-type main-sequence star, which means it is relatively high-mass compared to other stars like the Sun. Its mass is estimated to be about 1.8 times that of the Sun.
The sun is a low mass sequence star. It is classified as a G-type main-sequence star, which means it is in the middle of its stellar evolution and will remain stable for billions of years.
The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
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.
white dwarf
Yes, the core of a high mass star will collapse under immense gravitational pressure during a supernova explosion, forming a neutron star. Neutron stars are incredibly dense and composed primarily of neutrons, hence the name.
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.
