Abstract :
We report the analysis of the X-ray spectrum of AD Leo (dM3.5 V), observed by RGS and EPIC-MOS on board XMM-Newton and by LETGS on board Chandra. From the lightcurve the presence of flaring states and a quiescent part is noticed. Temperatures up to 20 MIA have been determined. A significant increase of the emission measure (EM) at high temperatures is determined for the flaring state. An indication for an Inverse First Ionization Potential (IFIP) effect has been found.
