At a GlanceAI
Catalogs 90 Sun–Venus resonant periodic orbits (with SRP) and maps their stability and bifurcations via monodromy eigenvalues.
SummaryAI
This paper fills a gap in three-body orbit catalogs by systematically identifying resonant periodic orbit families in the Sun–Venus system, a regime relevant to Venus flyby science, heliophysics monitoring, and surveillance-style mission concepts. Using a photogravitational planar CR3BP model, the authors extract fixed points from multiple Poincaré sections to seed periodic-orbit solutions, then continue them across Jacobi constant to build families and compute linear stability from monodromy-matrix eigenvalues. The result is a curated set of 90 resonant periodic orbits (87 with continued families) with stability and bifurcation flags, providing a practical starting library for future Sun–Venus trajectory design and for targeted follow-on work near bifurcation points.
Method SnapshotAI
Periodic resonant orbits are located from Poincaré maps in a solar-radiation-pressure–perturbed planar CR3BP, then continued in Jacobi constant and analyzed via monodromy eigenvalues.
BackgroundAI
Background in restricted three-body dynamics (CR3BP), Poincaré sections/maps, and linear stability of periodic orbits (state transition/monodromy matrices).
Interesting paper to learn about the dynamics of mmr with Venus in the CR3BP model. Advanced, require some background in celestial mechanics.
