Density-dependent suppression factors for dielectronic recombination rates #233

Open wtbarnes opened 1 year ago

wtbarnes commented 1 year ago

Currently, the dielectronic recombination rate calculations in fiasco is density-independent though in reality, dielectronic recombination may be suppressed at very high densities. In the IDL routines, there is a correction factor implemented to account for this density sensitivity. Looking at section 10.2 of the CHIANTI v10 paper, it looks like this was added in v10.

This report gives a brief description of this method and its implementation in CHIANTI: http://www.chiantidatabase.org/tech_reports/17_dr_suppress/chianti_report_17.pdf
