Normally such emission may be an indication of thermal emission by warm dust.

It is designed to directly detect young gas giants via their thermal emission.

Observing the star thermal emission is therefore crucial.

He proposed two sets of independent concepts in both circuit theory and thermal emission.

We get no reflections, no outline, and almost no thermal emissions.

The f/ratio is long to have a small secondary mirror, again to minimize the telescope's thermal emission.

The mirror coatings are chosen to have minimal thermal emission.

Reflectors can also be used to selectively reduce or eliminate unwanted thermal emission.

Thus thermal emission is responsible for a net loss of energy from the earth and atmosphere.

Regarding the thermal emission a large variety of different processes are prevalent.
