DOI: 10.1051/0004-6361/201936316
Abstract: Context. The original 1∕a-distribution is the only observational basis for the origin of long-period comets (LPCs) and the dynamical properties of the Oort Cloud. Although they are very subtle in the motion of these comets,… read more here.

DOI: 10.7566/jpsj.87.045001
Abstract: An equation for the curve described by a cord (thin rope) rotating around a straight line between its ends is obtained under the assumption that no external force such as gravity is exerted, and that… read more here.
