Correlation between exoplanet and star metallicity

الملخص EN

The metallicity [Fe / H] for several stars accompanied by Extra-solar planets were calculated and plotted as a function of stars mass (M*).

Results showed that masses of Extra-solar planets stars are well correlated with their metallicity .This relation could be explained by the equation : Y = -0.0045x + 0.065.

The metallicity limit is found to be in the range of (0.18 to 0.3), relative to the mass limit in the range of (0.76 to 1.44) MSun.

This criteria is a good tool that can be used by observers who are aiming for detecting Extra-solar planets.
