  • Metallicity - Wikipedia
    The metallicity of a star is most often expressed in terms of [Fe H], which represents the logarithmic ration of iron to hydrogen relative to the Sun's value
  • 金属性_百度百科
    金属性（英语：metallicity），指元素的气态原子失去电子变成气态阳离子倾向的大小。 失电子能力越强的粒子所属的元素金属性就越强；反之越弱，而其非金属性就越强。 金属性常表示元素的原子失去电子的倾向；元素的非金属性是指元素的原子得电子的能力。
  • METALLICITY中文 (简体)翻译：剑桥词典 - Cambridge Dictionary
    The greater a star's metallicity, the better its chances to have planets If the metallicity is too low, there is not enough material to build Earth-like planets The process can make planets with enriched metallicities as seen in our own solar system
  • Metallicity - an overview | ScienceDirect Topics
    Metallicity is defined as the amount of elements heavier than helium in a celestial object, commonly expressed through the ratio of iron to hydrogen, designated as [Fe H], on a logarithmic scale
  • metallicity
    Metallicity in its general sense is the ratio of metals (metals using astrophysics' odd definition: all elements except hydrogen and helium) in an astronomical object as compared to the whole, i e , compared to metals and non-metals combined
  • METALLICITY | definition in the Cambridge English Dictionary
    The greater a star's metallicity, the better its chances to have planets If the metallicity is too low, there is not enough material to build Earth-like planets
  • Metallicity
    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
  • 金属度_百度百科
    金属度是天文学中表征恒星金属元素含量的指标，英文名称为metallicity。 天文学中通常将所有比氢和氦重的化学元素统称为“金属”，金属度即指这些元素的比例或丰度。
  • Metallicity in Astronomy - Definition Detailed Explanation . . .
    Metallicity in astronomy refers to the abundance of elements heavier than helium in a celestial object, such as a star or a galaxy These “metals” include elements like carbon, oxygen, nitrogen, and iron, which are formed through nuclear fusion processes in stars
  • Metallicity - an overview | ScienceDirect Topics
    It was not merely the total metallicity that changed, but the relative abundances of different elements as well, thus changing the contribution of different elements to the total opacity of any given layer
