Schubart region HS.614

From Hristov, Hristova & Tanikawa (2026)

Schubart region HS.614 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 264.68 time units, published by Hristov, Hristova & Tanikawa (2026). Stable orbits that pass extremely close to a binary collision, descended from Schubart’s rectilinear orbit. They needed 100-digit arithmetic to find. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00000631 of each other at a top speed of 398, line up 456 times a period, and the computed loop closes to 6.3×10⁻²¹.
