Chorus waves, named for their bird-like chirping sounds, play a significant role in various astrophysical processes, including electron acceleration in radiation belts and auroral activity. These waves, predominantly observed in geospace and planetary atmospheres, have been studied for over 70 years. Their distinct features, such as rising and falling frequencies, have been linked to essential processes in the magnetosphere and ionosphere coupling, demonstrating their importance in energy transfer mechanisms. This highlights the complex dynamics within collisionless plasmas, driven predominantly by electromagnetic wave interactions with charged particles.
Chorus waves, which resemble birds' chirping, are critical for accelerating electrons in radiation belts and influencing auroras in geospace and planetary atmospheres.
The interactions between electromagnetic waves and charged particles are vital for energy transfers in collisionless plasmas, impacting various astrophysical phenomena.
