Asteroid Ryugu samples offer new insights into early solar system magnetism
To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread magnetic field of the solar nebula, which was generated by the weakly ionized nebular gas in the protoplanetary disk. During the formation or alteration, the magnetization of these materials can become locked in for billions of years, a phenomenon known as natural remanent magnetization (NRM). NRM m...
