Sentence examples for sequence lifetimes from inspiring English sources

Yet despite their diminutive physical properties, low-mass stars make up ~70% of all of the stars in the Milky Way and have main sequence lifetimes that exceed trillions of years.

Once stars have achieved their stable main--sequence configurations, they will spin--down appreciably during the main sequence lifetime (Skumanich 1972).

However, over the entire main sequence lifetime of the Sun (about 10 billion years), the Sun will only lose about 0.1% of its mass, which means that the Earth should move out by just ~150,000 km (small compared to the total Earth-Sun distance of ~150,000,000 km).

As can be seen in Table 1, the sample of solar proxies contains stars that cover most of the Sun's main sequence lifetime from ~100 Myr to 8.5 Gyr.

This results in a much shorter length of time in this stage compared to the main sequence lifetime.

This marks the end of the Sun's main sequence lifetime, and thereafter it will pass through the subgiant stage and evolve into a red giant.

Thus the star forms a self-regulating system in hydrostatic equilibrium that is stable over the course of its main sequence lifetime.

The Sun has been a main-sequence star for about 4.5 billion years and it will become a red giant in 6.5 billion years, for a total main sequence lifetime of roughly 1010 years.

The space between the stars in the Messier 87 galaxy is filled with a diffuse interstellar medium of gas, which has been chemically enriched by the elements ejected from stars as they passed beyond the end of their main sequence lifetime.

These stars are far more numerous than the solar type stars, have long main-sequence lifetimes, and have become prime targets for terrestrial planet searches in recent years.

Evidence is presented that the UC H II region phase of a massive star must last for a significant fraction of its main-sequence lifetime.
