Metallicity

GLOSSARY

METALLICITY

 
Measurement of the heavy element content in stars and in the interstellar medium. Metallicity measures the abundance of the elements heavier than hydrogen and helium (such as carbon, oxygen, iron, …). In stellar astrophysics, metallicity usually refers to the abundance of iron and is defined as the iron-to-hydrogen ratio.
