If it is using helium as fuel then it stopped being a main sequence star long long ago and if it has used up its helium and is now fusing carbon it has gone well outside the main sequence and is in the process of dying. All stars go through the process of being main sequence, so its a popular misnomer that a star has to be like the sun to be main sequence. The term refers to the time a star is converting hydrogen to helium, and any cycle after that changes what the star is called.
If you want to take the Sun as an example when it ends fusing hydrogen into helium, it will expand to a be a red giant about 250 times the size it is now and it will also lose about 30% of its mass.
Stars also continuously expel matter and winds into space, at the end of a stars life they either explode like a supernova (typical in stars much larger than the Sun), or each time a fuel source is used up, the star will expand until core temperatures and pressures rise enough to start a new fusion reaction. At this point, some of the outer layer is expelled and the star contracts to start its next life cycle. No star fuses elements heavier than iron.

< 0.25 solar masses they will degenerate directly to a white dwarf.
>= 0.25 solar masses, the will evolve onto the giant branch as a red giant.

∙ 10y agoThe main sequence star runs out if hydrogen "fuel" to use in fusion reactions in its core.
Then gravity causes the star to contract. Temperature and pressure increase in the core of the star. This enables new reactions to start, producing more energy.
If the star has enough mass, helium starts to be used as the fuel, together with hydrogen from outside the core.
Otherwise, hydrogen alone, from outside the core, can start to be used as fuel.
The star then expands, eventually becoming a giant star.

∙ 10y agoMost stars will end up as small WHITE DWARF stars, with all their nuclear fuel exhausted.
They still emit light because of energy derived from their gravitational collapse.
Eventually, after billions of years, they will become black dwarfs stars, emitting no visible light.
Stars with at least 8 times the Sun's mass end up as NEUTRON STARS or as
BLACK HOLES, after supernova explosions.

How do super massive rare stars end their life as?
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
Do low mass and medium mass stars eventually become neutron stars?
Low and medium sized stars will end up as white dwarfs.
Do most massive stars collapse into black holes?
Most stars end up as white dwarfs. A few become neutron stars. Even fewer become black holes.
How do the lives of the most massive stars end?
Less massive stars end up as white dwarfs. More massive stars end up as a supernova or a neutron star or for the really massive stars...as a black hole. As a star ends its time in the main sequence it either becomes a Red Giant and end its life as a White Dwarf or becomes a White Super Giant and ends its life in an explosion (supernova) and if it's really dense it becomes a neutron star or a black hole as mentioned above.
Do hot stars evolve more slowly than cool stars?
Hot stars are more massive than cooler stars and thus use up their available fuel much more quickly.

Which stars primarily end up as black holes?
The most massive stars become black holes.
How do super massive rare stars end their life as?
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
What happens as stars die?
Exactly what happens depends on the mass of the star. Low mass stars first expand into giants, then shrink to white dwarfs. Stars with a little more mass than the Sun end up as neutron stars; stars with considerably more mass with the sun end up as black holes.
When does bedew evolve Pokemon platinum?
There is no specific level that a Budew will evolve at. However, if you level it up on high happiness, you will end up with a Roselia. And if you use a Shiny Stone on the Roselia, you will get a Roserade.
