Both the temperature and composition determines the star's energy
emission at different wavelengths.

The picture which emerges is one of a twisting jet whose
emission is amplified
at different wavelengths at different times, by the «lighthouse effect.»
Marengo said the study looked
at two
different infrared
wavelengths: the shorter was consistent with a typical star and the longer showed some infrared
emissions, but not enough to reach a detection threshold.
To prove their concept of this multiplex spectral microgel analysis within a microfluidic flow, the team used «
different barcodes corresponding to
different emissions at specific
wavelengths and the fluorescence intensity of known microRNA concentration,» which was measured for calibrations of the specific microRNA being explored.
The radio
emission rose and fell several times, and the relative intensity
at different radio
wavelengths also changed.
In the tugging on the temperature profile (by net radiant heating / cooling resulting from radiative disequilibrium
at single
wavelengths) by the absorption (and
emission) by
different bands, the larger - scale aspects of the temperature profile will tend to be shaped more by the bands with moderate amounts of absorption, while finer - scale variations will be more influenced by bands with larger optical thicknesses per unit distance (where there can be significant
emission and absorption by a thinner layer).
In reality, each
wavelength of IR
emission has a
different altitude which is up in the stratosphere for some where GHGs have strong lines, and down
at the surface for others in the «window» region.
(Note, by the way, that what is true for a radiating object is that the amount of radiation emitted
AT ANY PARTICULAR
WAVELENGTH is an increasing function of the temperature, a fact that is not always obvious because people often tend to normalize the
emission curves when showing
emission curves for
different temperatures on the same graph.)
Because of the
different intramolecular forces between water molecules as vapor in air, water, and ice, the
wavelengths of
emission and absorption are shifted; some of the radiation from the water / ice droplets
at the top of a cloud can escape to space because the atmosphere above it is transparent
at its
wavelengths, whereas the same radiation from droplets
at the bottom of a cloud will be absorbed and re-emitted in random directions from the droplets above, including back down to the originating droplets.
