Petr 1991 paper - First attempt to follow fast pulses Kasparova et al 2009 setup - Initial problem formulation * discussion of "constant density" case - Karlicky test-particle code, rather than Emslie deterministic propagation (ie, get exact particle distribution function) * discussion of T/NT distribution function - Spitzer conductivity, Peres et al. 1982 thick emission, return current (but no He yet) * discussion of saturated heat flux (what does the return current do in the standard heat-flux scenario?) - Return current very important for ionization - Ionization via NLTE - 5 level + continuum for H, Fang et al nonthermal rates, time-dependent ESE calculation, looks OK - MALI technique for RT (Rybicki-Hammer, not Carlsson) Kasparova et al 2009 results - Ionization lags behind T increase - Saha ionization comparison; time-dependent calculation shows long recovery time that is quite different; NT rates have striking effect at lowest heights (eg 1000 km) * Discussion of proton temperature lag (Somov & Syrovatskii) - NT effects more important in the wings - Contribution functions show clear photospheric contribution in wings - Return current (runaway approximation) * Discussion of return-current physics, partial ionization, laboratory experience, Langmuir waves etc. - Return current losses dominate in upper chromosphere, reduce significance of NT - Confirm initial decrease of line center H-alpha - Ly-alpha shows time scales appearing for no clear reason, some sort of echo or resonance due to RT, not hydro? * Discussion of TRACE Ly-alpha and UV signatures in this context Microwave, FIR continua - ALMA, SMESE, KOSMA in Tibet - H, H- free-free contributions * Discussion of Planck function as source function for continuum - Time profiles, NT contributions - Attempt to find NT diagnostic tool not so successful * Discussion of line-to-continuum ratios for this purpose - Chen, Ding ~2006 on Ca/H signature Conclusions - Comparisons of Halpha, HXR etc on short time scales (Wroclaw SETIS observations) - Nice cartoon * Discussion of Cheng et al. (2006) diagnostic calculations, utility of He lines Fatima Introduction RADYN code - Abbett-Allred modifications - F9-F11 calculations - Free-streaming limit conduction Results - Constant input until code breaks - He plateau develops, non-explosive, hint of TR moving down at end * Discussion of upper boundary condition problem and final (cooling) states - F10 evolves faster - F11 run for about 2 sec * Discussion of input function (Karlicky, Fokker-Planck, stochasticity) - TRACE predictions - TRACE flare data, using correction by 1600A - 8-Sep-99 M1.4 example - 28-Feb-99 M6.6 example - Energetics: 1-2 x 10^22 erg/s total * Discussion - Ejection - Time history * Discussion of CIV contributions, timing of TRACE data - Ly-alpha line profiles from models show two peaks * Discussion suggets two velocity components - Contribution functions * Discussion of blue/red conventions and direction of flows - Energetics * Discussion of input to Labrosse code - Intensities Conclusions - Profiles and energetics agree with observations - Want to change heating functions * Discussion of deposition functions - Analysis of contribution functions - Addition of CIV etc optically thin
