Three-body periodic collisionless equal-mass free-fall orbits revisited
Ivan Hristov, Radoslava Hristova, Veljko Dmitrašinović +1
Li and Liao announced (2019) discovery of 313 periodic collisionless orbits' initial conditions (i.c.s), 30 of which have equal masses, and 18 of these 30 orbits have physical peri…
A Transit of Venus Possibly Misinterpreted as an Unaided-Eye Sunspot Observation in China on 9 December 1874
Hisashi Hayakawa, Mitsuru Sôma, Kiyotaka Tanikawa +6
Large sunspots can be observed with the unaided eye under suitable atmospheric seeing conditions. Such observations are of particular value because the frequency of their appearanc…
Periodic Orbits and Binary Collisions in the Classical Coulomb Three-Body Problem
Mitsusada M. Sano, Kiyotaka Tanikawa
In the helium case of the classical Coulomb three-body problem in two dimensions with zero angular momentum, we develop a procedure to find periodic orbits applying two symbolic dy…
A trial symbolic dynamics of the planar three-body problem
Kiyotaka Tanikawa, Seppo Mikkola
Symbolic dynamics is applied to the planar three-body problem. Symbols are defined on the planar orbit when it experiences a syzygy crossing. If the body i is in the middle at the…
The Rectilinar Three-body Problem using Symbol Sequence II. Role of the periodic orbits
Masaya Masayoshi Saito, Kiyotaka Tanikawa
We study the change of phase space structure of the rectilinear three-body problem when the mass combination is changed. Generally, periodic orbits bifurcate from the stable Schuba…
Correlation of macroscopic instability and Lyapunov times in the general three-body problem
Seppo Mikkola, Kiyotaka Tanikawa
We conducted extensive numerical experiments of equal mass three-body systems until they became disrupted. The system lifetimes, as a bound triple, and the Lyapunov times show a co…
