Most stars are main sequence stars that fuse hydrogen to form helium in their cores - including our sun. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

The Sun is very much a main sequence star, in the G-type category (G2V to be precise). It’s been fusing hydrogen for 4.6 ...

Many main sequence stars are also often referred to as “dwarf” stars. They can range greatly in luminosity, color, and size, from a tenth to 200 times the sun’s mass.

The Sun is very much a main sequence star, in the G-type category (G2V to be precise). It’s been fusing hydrogen for 4.6 billion years, but it still has almost three times as much as it has helium.

Our Sun is an average main-sequence star. ... creating a beautiful planetary nebula.High-mass stars create even more elements through fusion, such as neon, magnesium, ...

A low-mass star uses hydrogen fuel so sluggishly that they can shine as main-sequence stars for 100 billion to 1 trillion years — since the universe is only about 13.7 billion years old ...

All stars spend the majority of their lives as so-called main-sequence stars. Consequently the vast majority of stars—90% or so—are undergoing hydrogen-helium fusion at any given time.

Like all main-sequence stars, the majority of the sun's mass is made up of hydrogen, with some helium and traces of heavier elements , which are referred to as the metallicity or “Z” of a star ...

These stars can range from around a tenth of the mass of our Sun all the way up to 200 times as massive, and how long a star will stay in the main sequence phase depends on its size.

Main sequence stars are supported by nuclear fusion in their cores. The higher the mass, the faster a star uses its fuel and the shorter its lifetime on the stable main sequence is.

Main-sequence stars The exact length of the main-sequence stage depends on the star’s mass: the lower the mass of the star, the longer it takes to burn up all its hydrogen.
