Two chargeand current neutral plasma beams are modelled with a onedimensional PIC simulation. The beams are uniform and unbounded. The relative speed between both beams is 0.4c. One beam is composed of electrons and protons and one out of protons and negatively charged oxygen (dust). All species have the temperature 9 keV. A Buneman instability develops between the electrons of the first beam a...

For more than 12 hours beginning on January 18, 2021, continuous narrowband electrostatic emissions were observed Parker Solar Probe near 20 solar radii. The <1000 Hz frequencies well below the local ion plasma frequency. Surprisingly, consisted of wave packets with shock-like envelopes, appearing repetitively at a ~1.5 rate. This repetitiveness correlated and was in phase low frequency electro...
