Example sentencesExamples
- The average chromospheric activity level in the early F-type stars is statistically identical in the three clusters and in field dwarfs.
- This expansion of chromospheric plasma up into the corona during a flare is generally called chromospheric evaporation.
- Thus, detection of this resonance will provide an important new constraint on chromospheric models.
- As the Sun went dark the corona became visible to all, although not much of a chromospheric display was seen, with only one notable prominence, perhaps two close by each other.

Origin

Mid 19th century: from chromo-² 'colour' + sphere.
