CHIANTI: A Database for Astrophysical Emission Line Spectroscopy
CHIANTI Version 3.0 Released !
CHIANTI has been extended to X-ray wavelengths below 50 Å
The Chianti producing region of Italy (click for a larger version)
CHIANTI consists of a critically evaluated set of atomic data necessary
to calculate the emission line spectrum of astrophysical plasmas. The
data consists of atomic energy levels, atomic radiative data such as
wavelengths, weighted oscillator strengths and A values, and electron
collisional excitation rates. A set of programs that use these data to
calculate the spectrum in a desired wavelength range as a function of
temperature and density are also provided. These programs have been
written in Interactive Data Language (IDL) and this html document
provides a description of these various programs.
