Diagnostics of stellar flares from X-ray observations : from the decay to the rise phase

  title={Diagnostics of stellar flares from X-ray observations : from the decay to the rise phase},
  author={Fabio Reale},
Context. The diagnostics of stellar flaring coronal loops have been so far largely based on the analysis of the decay phase. Aims. We derive new diagnostics from the analysis of the rise and pe ak hase of stellar flares. Methods. We release the assumption of full equilibrium of the flaring l oop at the flare peak, according to the frequently observed de lay b tween the temperature and the density maximum. From scaling laws a nd hydrodynamic simulations we derive diagnostic formulas as a… CONTINUE READING
