Schematic view of our scenario. An hourglass-shaped magnetic-field configuration focuses cosmic rays from a molecular cloud core to a protoplanetary disk. The purple oval represents the area from which the disk can receive cosmic-ray particles. The magnetic fields are stretched to azimuthal direction by shearing motion.
