(iron X-ray line)

The K-line (or iron K-line or iron Kα) is an iron spectral line that is useful in classifying stars.

It is also useful in studying the X-ray emission from active galactic nuclei. In the latter case, it can be iron fluorescence powered by even higher energy X-ray photons which are part of a very high temperature thermal emission due to the energy release of accretion.
