metallicity

The star's metallicity is more than double that in the Sun.

The age of the star is slightly older and have significantly higher metallicity than our Sun.

The age of the star is younger and intermediate in metallicity.

There is no significant spread in metallicity throughout the galaxy.

It is more massive and slightly smaller than the Sun with high metallicity.

If the metallicity is known the uncertainty in age does not exceed 15%!

Despite its younger age, it has slightly lower metallicity, approximately 90%.

Its metallicity is nearly 50% more than the Sun.

Stars with higher metallicity such as this are more likely to host planets.

It has about half the metallicity of our Sun.

But near the core the metallicity was becoming higher than optimum.

In order to produce today's metallicity, early galaxies must have been significantly more powerful than they are today.

The metallicity rises from the outer region towards the centre.

The metallicity of these stars is also very low at 2.1, which means that they contain 110 times less heavy elements than the Sun.

It has the lowest metallicity of any known star.

It is a Population I star with metallicity of 55% greater than solar.

The companion is an old, active red dwarf star that has a relatively high metallicity.

A moving group is distinguished by its members having about the same age, composition (or metallicity) and motion through space.

Qualities considered include variability, mass, age, metallicity, and close companions.

The latter have longer periods, strong metallicity and large amplitudes.

Kepler-5 is larger and more massive than the Sun, but has a similar metallicity, a major factor in planet formation.

The star was found to be slightly hotter than the Sun, but has a similar metallicity and is therefore not much more massive.

No such metallicity biases are known for short gamma-ray bursts.

Metallicity is the abundance of elements other than hydrogen and helium.

This, in combination with their low metallicity, shows that the pair belongs to the old disk population.
