Solar Wind Protons in the Diamagnetic Cavity at Comet 67P/Churyumov-Gerasimenko.

Article Synopsis
- The plasma environment around a comet has different regions, including the solar wind ion cavity (lacking solar wind ions) and the diamagnetic cavity (unmagnetized plasma in the inner coma).
- Recent observations have revealed that protons with solar wind energy can actually be found inside the diamagnetic cavity, which contradicts previous theories that they shouldn't be there.
- The presence of these protons seems to be connected to specific solar wind conditions, particularly when the solar wind velocity aligns with the interplanetary magnetic field, suggesting a unique interaction between the comet and solar winds under special circumstances.
