photospheres

Well, the turbulence evidently went deeper than the photospheres.

Alexander Von Humboldt, in speaking of stars that have thus disappeared, says that "their disappearance may be the result of their motion as much as of any diminution of their photometric processes (whether on their surfaces or in their photospheres), as would render the waves of light too weak too excite the organs of sight."

They possess, it would appear, photospheres radiating all kinds of light, and differ from each other mainly in the varying qualities of their absorptive atmospheres.

Objects of the kind do not, then, gain light through the closing-up of dusky chasms in their photospheres, but by an actual increase of surface-brilliancy, together with an immense growth of these brilliant formations -- prominences and faculæ -- which, in the sun, accompany, or are appended to spots.

Emission from the photospheres of stars dominates the 9 micrometres catalogue, where the galactic disc and nuclear bulge are clearly visible, whereas dust and star formation in the disc of our Galaxy become are more prominent at 90 micrometres.

Thus the subject is the concern of geophysical and environmental scientists (in dealing with atmospheric jet streams, ocean currents, and the flow of rivers, for example), of astrophysicists (in studying the photospheres of the sun and stars or mapping gaseous nebulae), and of engineers (in calculating pipe flows, jets, or wakes).

Several papers deal with stellar activity and report the detection of spots in the stars 'photospheres (Mosser et al.), giving access to the stars' rotation rate.

They identify three such objects from the presence of warm molecular gas features in their photospheres (or envelopes), features that are familiar from studies of young stars much closer to earth.
