A glowing, transparent layer of gas surrounding the photosphere of a star, especially the sun. The sun's chromosphere is several thousand miles thick and is composed mainly of hydrogen.

IST), while examining the sun's lower atmospheric layer just above the surface, called chromospheres, scientists observed a moderate flare, labelled an M-class flare, which is the second strongest class of flare after X-class, as (http://www.
We used the capsize 3 activity assay, which involves spectro-photometric detection of the chromospheres p-nitroanilide after cleavage from the substrate Ac-DEVD-p-nitroanilide.
Immediately after removal from the water bath, the test tubes were cooled in ice bath and 4 ml toluene was added to separate chromospheres.
Among the topics are the physical properties of red supergiants, the dying carbon star U Antliae, interferometric observations of supergiants, the circumstellar-interstellar boundary around evolved stars, chromospheres and the winds of cool supergiants, polarization from the structured envelopes of cool evolved stars, and a cool star mass loss rate study.
It is thus able to determine the nature and position of many of the different components of the skin, including key chromospheres within the skin.
Eddington recognized the great spatial extent of the chromosphere and pondered on how this material was supported [9, p.
In order to further increase this scale height to the levels observed, it was hypothesized that the chromosphere had to be heated, either through turbulent motion, wave motion, magnetic fields, or 5-minute oscillations [277, p.
Hence, the spatial extent of the chromosphere constitutes one of the most elegant observations relative to the existence of a condensed solar photosphere.
The chromosphere also supports weak continuous emission.
The weak continuous spectrum of the chromosphere [1518] has drawn the attention of solar observers for over 100 years [19-22].
Bhatnagar outlines that "Between the upper layer of the chromosphere and corona (although the demarcation is not sharp) lies the 'transition layer ', where the temperature rises very steeply, from about 25 000 to 500 000 K in height difference of just 1 000 km " expanding the extent of the transition region by a factor of 10 [8, p.
Harold Zirin, in candid fashion, reminds his readers that anyone with a ruler can establish that the chromosphere can attain elevations of at least 5 000 km from H[alpha] emissions [9].
