Large-scale chaos in restricted hierarchical triples driven by short-range forces
Xiaoyan Leng, Hanlun Lei
Context: The eccentric von Zeipel-Lidov-Kozai effect, which is widely applied to diverse astrophysical settings, can drive the inner binary to extremely high eccentricities, where…

High-order expansions of multi-revolution elliptic Halo orbits in the elliptic restricted three-body problem
Xiaoyan Leng, Hanlun Lei
Multi-revolution elliptic Halo (ME-Halo) orbits are a special class of symmetric and periodic solutions within the framework of the elliptic restricted three-body problem (ERTBP).…
