|91. First study on the X-ray imaging of Kelvin-Helmholtz waves at the magnetopause
The solar wind charge exchange (SWCX) process occurs when a high charge state solar wind ion (e.g., O7+) encounters a neutral atom or molecule (e.g., H) and picks up an electron in an excited state. The ion then emits a photon when it decays to a lower energy state and thus may lead to the sate...
