| Abstract: |
We compare the coronal properties during flares on active low mass stars CN Leonis, AB Doradus A and Proxima Centauri
observed with XMM-Newton. From the X-ray data we analyze the temporal evolution of temperature, emission measure and coronal abundance.
The nature of these flares are with secondary events following the first flare peak in the light curve, raising the question
regarding the involved magnetic structure.
We infer from the plasma properties and the geometry of the flaring structure that the
flare originates from a compact arcade rather than in a single loop. |
