Photo taken in France during the 1999 solar eclipse

The stellar atmosphere is the outer region of the volume of a star, lying above the stellar core, radiation zone and convection zone.


The stellar atmosphere is divided into several regions of distinct character:

During a total solar eclipse, the photosphere of the Sun is obscured, revealing its atmosphere's other layers.[1] Observed during eclipse, the Sun's chromosphere appears (briefly) as a thin pinkish arc,[11] and its corona is seen as a tufted halo. The same phenomenon in eclipsing binaries can make the chromosphere of giant stars visible.[12]
