Context. Near-Earth asteroid 162173 (1999 JU3) is a potential flyby and rendezvous target for interplanetary missions because of its easy to reach orbit. The physical and thermal properties of the asteroid are relevant for establishing the scientific mission goals and also important in the context of near-Earth object studies in general. Aims. Our goal was(More)
The calcite form of calcium carbonate CaCO₃ undergoes a reversible phase transition between Rc and Rm at ~1240 K under a CO₂ atmosphere of ~0.4 MPa. The joint probability density function obtained from the single-crystal X-ray diffraction data revealed that the oxygen triangles of the CO₃ group in the high temperature form (Phase V) do not sit still at(More)
