Creating a CLOUDY Compatible Database with CHIANTI version 10 Data

Chamani M. Gunasekera, Marios Chatzikos, Gary J. Ferland

Atomic and molecular data are required to conduct detailed calculations of microphysical processes performed by CLOUDY to predict the spectra of a theoretical model. One of the thr…

Self-Consistent Grain Depletions and Abundances II: Effects on strong-line diagnostics of extragalactic H II regions

Chamani M. Gunasekera, Xihan Ji, Marios Chatzikos +2

The depletion of elements onto dust grains is characterized using a generalized depletion strength F∗​ for any sightline, and trend-line parameters AX​,BX​ and zX​. The para…

Self-consistent grain depletions and abundances I: The Orion Nebula as a test case

Chamani Gunasekera, Xihan Ji, Marios Chatzikos +2

Atomic species in the interstellar medium (ISM) transition out of their gas phase mainly by depletion onto dust. In this study, we examine if there is any change to the spectral li…
