Dynamics of flaring loops. II : Flare evolution in the density-temperature diagram

Abstract

The evolution of basic thermodynamic parameters of a single flaring solar loop has been investigated in terms of density-temperature diagram. A grid of hydrodynamic models has been calculated for this purpose using the Palermo-Harvard code. The calculated models differ in their initial conditions and the form of the energy input i.e. the heating rate value, the heating duration, the assumed time profile. We have considered the consequences of variation of these model parameters on the evolutionary paths in the density-temperature diagrams
