- A team of astronomers from the Indian Institute of Geomagnetism (IIG) have found the first evidence of the presence of solitary waves or distinct electric field fluctuations on Mars.
- The study of these waves is crucial as they directly control particle energization, plasma loss, transport etc through wave particle interactions".
- Earth has a magnetosphere around it which is basically a shield around a planet made of magnetic field.
- Mars only has a weak magnetic field from its crustal magnetic sources.
- This allows the solar winds to interact with the Martian atmosphere and create solitary flows.
- Solitary waves are distinct electric field fluctuations (bipolar or monopolar) that follow constant amplitude-phase relations.
