Description
Magnetospheric jets are regions of enhanced dynamic pressure in the magnetosheath. They are usually associated to the region behind a quasi-parallel shock and have been well documented at Earth.
However in recent years there have been efforts to identify these structures in other magnetosheaths as well. For example, recently it has been shown that they exist in the Martian magnetosheath. As the cometary plasma environment has very similar characteristics as the Martian one, it stands to reason that these structures also exists at Comets.
We present a study that uses Rosetta magnetic field and density measurements to identify possible jet structures.
We find that they are ubiquitous especially in the plasma environment where Rosetta is probably in the magnetosheath. Their occurrence matches what was found for similar events at Mars. The magnetic field can correlate or anti-correlate with the density enhancement, just like it is observed at Earth and Mars.
