Emission Lines

From RHESSI Wiki

RHESSI observes X-rays down to 3 keV which includes a number of emission lines. They consist mostly of highly ionized Fe lines. There are no lines above about 10 keV.

Lines in RHESSI Spectra
Figure 1: A synthetic thermal spectra created with Chianti showing the thermal continuum along with line emission. The red curve shows what RHESSI should observe.
Figure 2: Figure 1 from Phillips 2008 which shows the Iron and Iron-Nickel complex identifying each line
Figure 3: A close up of the Iron complex.
Figure 4: A close up of the Iron-Nickel complex along with some higher energy Iron lines. Due to small flux in the higher energy lines, RHESSI is only likely to observe the Iron-Nickel complex as can be seen from the (red) RHESSI overlay.
