Their new features activate many discussions: for example, hexagonal close-packed iron may be nearly isotropic, which requires a new mechanism of inner core anisotropy; thermal conductivity may be 2-3 times larger than the previous estimates, which inhibits vigorous convection in the outer core and requires a young inner core. We can find the Earth's core is still a mysterious region. As for the core of the other planetary body, the Moon's core is discovered by using Apollo seismic data, which should be confirmed and further constrained by new scientific project with modern techniques. Here we would like to have an opportunity to discuss recent advances and exchange interesting ideas about the Earth's and planetary cores. We welcome any papers from any discipline, such as mineral physics, geomagnetism, geodynamics, seismology and any other relevant fields. 英文 Recently, the physical properties relating to the Earth's core are revisited under exact conditions.
