High-Frequency Plasma Waves – Mars

April 18 , 2024 221 days 260 0
  • 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.
