The abundance of elements other than hydrogen and helium, what astronomers term the star's metallicity, is only around half that in the Sun.

This system is what astronomers term a double-lined spectroscopic binary.

It has a higher than solar abundance of elements other than hydrogen and helium; what astronomers term a metal-rich star.

The abundance of elements other than hydrogen or helium, what astronomers term the star's metallicity, is similar to the proportion in the Sun.

The abundance of elements other than hydrogen and helium, what astronomers term the metallicity, is unusually high in this star when compared to the Sun.

The abundance of elements other than hydrogen or helium, what astronomers term the metallicity, is approximately the same as in the Sun.

Like most halo stars, it has a low abundance of elements other than hydrogen and helium-what astronomers term a metal-poor star.

Compared to the Sun, this star appears deficient in elements other than hydrogen and helium-what astronomers term the star's metallicity.

There is some uncertainty in the scientific press about the enriched of elements heavier than hydrogen than the Sun; what astronomers term the metallicity.

Compared to the Sun, this star has a lower abundance of elements other than hydrogen and helium, what astronomers term the star's metallicity.
