SUMMARY:Modelling and Interpreting Non-LTE Emission from Isolated Solar St

DESCRIPTION:Modern simulations of isolated structures such as solar promin
 ences and filaments demonstrate increasingly complex and realistic behavio
 ur down to fine spatial scales. However\, the lack of self-consistent opti
 cally thick radiation treatment limits their comparison to observations. T
 his is primarily due to the difficulty converting magnetohydrodynamic (MHD
 ) simulation cubes into emergent spectra for spectral lines that form outs
 ide of local thermodynamic equilibrium (LTE). Whilst complex\, these spect
 ral lines are the primary vector by which these structures can be interpre
 ted and are key to exploiting cutting edge solar observatories.\n\nIn this
  talk I will discuss the formation of spectral lines outside of LTE (non-L
 TE)\, and the application of these techniques to models of isolated solar 
 structures. I will also touch on potential pitfalls of a column-by-column 
 approach to synthesis and discuss a new approach for scaling to three-dime
 nsional integrated radiative MHD simulations for these structures.\n\n\n
