    "abstract": "The Lagrangian, the Hamiltonian and the constant of motion of the\ngravitational attraction of two bodies when one of them has variable mass is\nconsidered. This is done by choosing the reference system in one of the bodies\nwhich allows to reduce the system of equations to 1-D problem. The trajectories\nfound in the space position-velocity,(x,v), are qualitatively different from\nthose on the space position-momentum,(x,p).",
