CHIANTI consists of a critically evaluated set of up-to-date atomic data, together with user-friendly programs written in Interactive Data Language (IDL) to calculate the spectra from astrophysical plasmas.

The CHIANTI package is freely available to all researchers.
If you use the package, we only ask you to appropriately acknowledge CHIANTI .

CHIANTI team receives award from the Royal Astronomical Society!

On January 8 2010 the CHIANTI team were awarded the Group Achievement Award for Geophysics by the Royal Astronomical Society (UK). The citation was:

"The Group Achievement Award for Geophysics is given to the CHIANTI consortium, the team of scientists who have developed the 'Atomic Database for Spectroscopic Diagnostics of Astrophysical Plasmas.' This is a powerful tool for scientists who use the dispersion of light by wavelength (spectroscopy) to measure the properties of astronomical objects, including their composition, temperature, density and magnetic field strength. The analysis requires detailed knowledge of a large range of atomic elements. The CHIANTI consortium's achievement is the establishment of a systematic, easy-to-use and publically available database to assist this process, with a huge impact on solar and stellar physics."

A full press release is available from the RAS website.

We are grateful to individual scientists and funding agencies for their support.
