Scientists from the Indian Institute of Geomagnetism had studied high-frequency plasma waves in Mars' upper atmosphere using data from NASA's MAVEN space craft.
These waves may include electron oscillations known as Langmuir waves or upper-hybrid type waves.
They propagating either parallel or perpendicular to the background magnetic field in the Martian magneto sheath region.
These waves play a significant role in various plasma phenomena, influencing energy transfer, particle acceleration, and the behavior of charged particles within plasmas found in space.
Plasma waves are common around Earth and other planets, influencing particle dynamics.
Mars lacks its own magnetic field but has a weak induced magnetosphere exposed to solar wind.
