Broadband microwave sub-second pulsations in an expanding coronal loop of the 2011 August 10 flare

Original language description

We studied the characteristic physical properties and behavior of broadband microwave sub-second pulsations observed in an expanding coronal loop during the GOES C2.4 solar flare on 2011 August 10.The complex microwave dynamic spectrum and the expanding loop images were analyzed with the help of SDO/AIA/HMI,RHESSI, and the STEREO/SECCHI-EUVI data. The EUV intensity of the expanding loop increased just before the radio source triggering. Two EUV bidirectional flows that are linked with the start time of the loop expansion. Their positions were close to the radio source. We demonstrate that periodic regime of the electron acceleration in a model of the quasi-periodic magnetic reconnection might be able to explain physical properties and behavior of the sub-second pulsations. The depolarization process of the microwave emission might be caused by a plasma turbulence in the radio source. Finally, the observed EUV flows might be linked with reconnection outflows.
