Some of the charged particles in the solar wind can reach the surface of M star and transfer enough energy to the surface particles of M star so that the latter can escape from the surface of M star and escape into the atmosphere of M star
In order to determine these escaped particles, the scientists obtained the following information through three experiments: experiment 1: either X particle or Y particle; experiment 2: either Y particle or Z particle; experiment 3: if it is not Z particle, it is not Y particle
This particle is not an X particle.
