IRIS diagnostics of solar flares

Finding a definitive model for flares still remains one of the most challenging problems in astrophysics. Spectroscopic instruments such as Hinode/EIS and IRIS allow a diagnosis of the fundamental parameters of the plasma (including flows, density, temperature and emission measure), which can then be matched against the results of competing theoretical models. This talk will focus on flare diagnostics that can be obtained from IRIS, in particular addressing long-standing issues regarding the chromospheric evaporation process during the impulsive phase of flares.
