chromosphere
chromosphere Astron. (ˈkrəʊməsfɪə(r)) [f. chromo- 2 + sphere. The form of this word has been objected to in favour of chromatosphere. But although the latter shows the usual Greek type of compounds from ns. in -µα, -µατ-, the shortened form was also used: see e.g. the compounds in σπερµο- for σπερµα... Oxford English Dictionary

HD 9446
It is roughly two billion years in age and has an active chromosphere. The amount of activity measured in the chromosphere corresponds to a star with a rotation period of about 10 days. wikipedia.org

HD 12661
As a star ages it slows its rotation and diminishes the amount of magnetic activity in its chromosphere. Based upon the chromosphere emission of HD 12661, it is older than the Sun with an estimated age of roughly seven billion years. wikipedia.org

The variability is attributed to large-scale magnetic activity on the chromosphere (in the form of starspots) combined with a rotational period that moved The high rotation period and active chromosphere are indicative of a relatively young star. wikipedia.org

HR 6806
In 1988, it was noticed that the star had an inactive chromosphere, with a surface magnetic field strength of only 1,500 G. From 1990 activity in the chromosphere increased, inline with a 16 year stellar cycle previously observed. wikipedia.org

色球
色球或色球层（英语：Chromosphere，词义是有颜色的球）是太阳大气层主要三层中的第二层，厚度大约2,000公里，位于光球层的上方和过渡区的下方。 色球层的密度相当低，它的起始处，也就是色球层的底部，密度只有光球的10−4倍；相较于地球的大气层，更只有10−8。 Animated explanation of the temperature of the Chromosphere (and Transition Region) (University of South Wales). 太阳 恒星 wikipedia.org

Solar plage
A plage is a bright region in the Sun's chromosphere, typically found in and around active regions. of plage is confined to the intergranular lanes in the photosphere with a strength of around 1500 G, but expands into a volume filling canopy in the chromosphere wikipedia.org

Solar prominence
While the corona consists of extremely hot plasma, prominences contain much cooler plasma, similar in composition to that of the chromosphere. Many prominences also have smaller structures referred to as barbs that similarly diverge from the spine towards the chromosphere and photosphere. wikipedia.org
