Sentences with phrase «do photospheres»

We're throwing in the Nexus 4 for this comparison because it also can do Photospheres out of the box.

Not exact matches

The older idea that acoustic waves flowing out of lower levels heats the corona was abandoned in the 1970s, when the Orbiting Solar Observatory 8 spacecraft did not see such waves in the chromosphere, the layer just above the photosphere (the apparent «surface» of the sun in visible light).

A related question is why, if the corona is so hot, it does not heat up the photosphere until it has an equally high temperature.

It will do this via high - speed (sub-second timescales) spectroscopic and magnetic measurements of the solar photosphere, chromosphere and corona.

In reality, the stellar spectrum does not cancel out in transmission spectroscopy, because the first - order approximation described above confusingly equates two different light sources: the stellar disk (the spectrum of which is observed before the transit) and the actual light source, which is just a very small fraction of the stellar disk — the projection of the transit chord onto the stellar photosphere (see figure).

As we pass up through the photosphere, the temperature drops and the gases, because they are cooler, do not emit as much light energy.

This integral can be done at the OD = 1 point, because that is the photosphere radius for the IR, and for the non-GHG frequencies it doesn't matter where you do the integral.

2) As you say, when more GHG is added, the altitude of the photosphere rises (I don't see that the tropopause would rise), and its temperature is reduced: so less power must be radiated away.

But the downward radiation, which is sourced by the upper atmosphere, does not: At the radius of the old photosphere, before the addition of the GHG, the downward radiation was rather small, because there wasn't much of the sourcing GHG above it.
