Scientific paper

The first version of the CHIANTI atomic database for astrophysical spectroscopy was released in 1997 and the most recent version in 2009. Recent progress with CHIANTI will be described.
Based on the ionization rates developed by Dere (2007) and the radiative and dielectronic recombination rates of Badnell and colleagues, a new set of ionization balance calculations has been calculated. These show some substantial difference from previous calculations.
A suite of Python programs, ChiantiPy, has been developed to allow users to use the CHIANTI database to calculate spectral line and continuum intensities in an object-oriented manner. This package is also the basis for a developmental web server that can show the results of specifically requested calculations through a user web browser.
The direction of future work with CHIANTI will be outlined.
