    AnnotationMagnetic isolated large amplitude depressions in the interplanetary magnetic field are commonly observed in the solar wind. Some of these magnetic structures are accompanied by bursts of electrostatic waves close to electron plasma frequency. Combining STEREO/WAVES and IMPACT data we are able to accurately localize the waves emission. We show that they also appear inside kinetic holes, themselves situated inside larger holes. We provide, for the first time, the detailed waveform of the waves that reveal their very bursty nature. These results are complemented by CLUSTER data, which allow to resolve the electron distribution and obtain a better description of spatio-temporal variations in Langmuir wave activity. Such observations are confronted to different emission mechanisms.
