Is the milky way a main sequence star?

Answer 1

All stars that are in hydrostatic equilibrium are on the main sequence, where outward thermal pressure from the hot core is balanced by the inward gravitational pressure from the overlying layers.

Answer 2

A lot would depend on the age of the star.

Stars in the Milky Way start off with around 71% hydrogen and 27% helium, but as the star fuses hydrogen into helium throughout it's life, the percentage of hydrogen will diminish while the percentage of helium will increase.

Answer 3

Yes - that's precisely why it is called "main sequence" - on a scatter graph, most stars are along a certain curve, which has been given this name.

Answer 5

Generally a blue star is on the main sequence.

However, the colour of a star is related to its temperature. It's temperature is related to the mass of the star - the higher the mass (Size) the hotter the star is.

A star on the main sequence [See related question] is fusing hydrogen into helium to produce energy.

Answer 6

No, the Milky Way is not a main sequence star. The Milky Way is actually a barred spiral galaxy that consists of billions of stars, including our Sun, which is a main sequence star.

Answer 7

Approximately 90% of all stars are on the main sequence.

Answer 8

Probably all of them. A star in "main sequence" is when they convert hydrogen into helium.

Answer 9

When they start fusing hydrogen into helium.

Answer 10

Main sequence stars are Type V (roman numeral 5).
