And it turns out once again that spectral sensitivity is very important here.

The main star is of magnitude 4.33 and spectral type A0p, while the companion is magnitude 5.23 and belongs to spectral class A3m.

In astronomy, stellar classification is the classification of stars based on their spectral characteristics.

These techniques include spectroscopic methods such as nuclear magnetic resonance (NMR) and X ray diffraction.

This would be important in order to eventually establish correlations between observed spectral properties and internal structure

Every species of plant reflects a unique combination of wave lengths, called spectral signatures that act like different chords on a piano but use light instead of sound.

Just give us a sign!

And later we went to study the spectral stars to see is there anything strange with these objects.

In this exercise you have to compare 2 given fractions by choosing the correct comparison sign. You can change the comparison sign by just clicking on the button showing the sign.

Send me your sign.

That's the signal to get going.

I guess that's my cue.

Wait for my signal.

Send out the success code words.

I'll give you the goahead.

As it expands, it will go through the F, G, K and M spectral types.

Detection and discovery Transits Spectroscopic studies first revealed the presence of a planet around HD 209458 on November 5, 1999.

That was a useful signal.

You ran a red light.

This is the independence flag, a sign of refusal of any attempt at exploitation

I see this plus sign.
