Regularization of the Hill four-body problem with oblate bodies

  title={Regularization of the Hill four-body problem with oblate bodies},
  author={Edward Belbruno and Marian Gidea and Wai-Ting Lam},
We consider the Hill four-body problem where three oblate, massive bodies form a relative equilibrium triangular configuration, and the fourth, infinitesimal body orbits in a neighborhood of the smallest of the three massive bodies. We regularize collisions between the infinitesimal body and the smallest massive body, via McGehee coordinate transformation. We describe the corresponding collision manifold and show that it undergoes a bifurcation when the oblateness coefficient of the small…

Study of the ejection/collision orbits in the spatial RTBP using the McGehee regularization

Summary: In this paper we analyse the McGehee regularization of the collision in the spatial Restricted three-body problem (3D RTBP). As a particular application, we study the ejection (collision)

Surface gravity of rotating dumbbell shapes

We investigate the problem of determining the shape of a rotating celestial object – e.g., a comet or an asteroid – under its own gravitational field. More specifically, we consider an object

Ejection–Collision Orbits in Two Degrees of Freedom Problems in Celestial Mechanics

The existence of different types of ejection-collision orbits, that is, orbits that start and end at total collision, are proved based on the transversality of 2-dimensional invariant manifolds and on the behavior of the dynamics on the total collision manifold.

Hill Four-Body Problem with Oblate Bodies: An Application to the Sun–Jupiter–Hektor–Skamandrios System

We consider a restricted four-body problem, with a precise hierarchy between the bodies: two larger bodies and a smaller one, all three of oblate shape, and a fourth, infinitesimal body, in the

Ejection-collision orbits with the more massive primary in the planar elliptic restricted three body problem

The main goal of this paper is to give an approximation to initial conditions for ejection-collision orbits with the more massive primary, in the planar elliptic restricted three body problem when

Regularization and the artificial Earth satellite problem

Some of the properties of singularities of a system of differential equations, which includes several formulations of the artificial Earth satellite problem, are derived. Using them, it is shown that

Collective branch regularization of simultaneous binary collisions in the 3D N-body problem

In this work we study simultaneous binary collision (SBC) singularities of M⩽N∕2 binaries in the three dimensional classical gravitational N-body problem. We show the following: (1) In the
