From other sources the metallicity is around -2.3.
Their metallicity is similar to that of the Sun.
It is metal-rich with a metallicity of~= -0.8.
The star's metallicity is more than double that in the Sun.
Only population III stars, with very low metallicity, can reach this stage.
It has a metallicity of -1.8, a significantly low number.
The small companion is an active red dwarf star that has a relatively high metallicity.
During the starburst, the metallicity of WIM rose from~ -2.2 to -1.3.
The metallicity of Sextans B is rather low, with a value of approximately Z 0.001.
The latter have longer periods, strong metallicity and large amplitudes.
Proper metallicity and size are also very important to low luminosity variation.
Stellar characteristics of importance include mass and luminosity, stable variability,and high metallicity.
Also, the metallicity of Sakurai's object in 1996 was similar to that of V605 Aquilae in 1921.
The explanation of their underluminosity lies in their low metallicity: these stars are unenriched in elements heavier than helium.
The metallicity of Kepler-40, 0.10, means that it has 25.9% more iron than is measured in the Sun.
It is thought that even in our own galaxy, mergers of old low metallicity stars may form massive stars capable of creating a pair instability supernova.
Metallicity of at least 40% solar( -0.4) is required for the formation of an Earth-like terrestrial planet.
This raises the question of whether there is a correlation between a radial horizontal-branch gradient and the metallicity dispersion between dwarf spheroidal galaxies.
In order to produce today's metallicity, early galaxies must have been significantly more powerful than they are today.
Visually, the tip of the red giant branch occurs at about absolute magnitude -3 andtemperatures around 3,000 K at solar metallicity, closer to 4,000 K at very low metallicity. .
The metallicity of Andromeda V is above the average metallicity to luminosity ratio of the Local Group's dwarf galaxies.
Because both stars are fairly similar to the Sun(for example, in age and metallicity), astronomers have been especially interested in making detailed searches for planets in the Alpha Centauri system.
The metallicity of these old stars is also very low at≈ -2.08± 0.02, which means that they contain 110 times less heavy elements than the Sun.
Astronomers are able to determine if stars are members of a kinematic group because they share the same age, metallicity, and kinematics radial velocity and proper motion.
Its higher metallicity compared to the SMC suggests that star formation activity has continued for a longer time period.
The table below shows the typical lifetimes on the main sequence(MS), subgiant branch(SB), and red-giant branch(RGB),for stars with different initial masses, all at solar metallicity Z 0.02.
The metallicity is very low, at about =-1.6 to -1.9 meaning that Antlia Dwarf contains 40-80 times less heavy elements than the Sun.
This supports a hypothesis concerning the possibility that the metallicity of stars during their births may determine whether a protostar's accretion disk forms gas giants or terrestrial planets.
The metallicity of these old stars is low at =-2.1± 0.2, which means that they contain 120 times less heavy elements than the Sun.
