The Restless Universe Applications of Gravitational N-Body Dynamics to Planetary Stellar and Galactic SystemsCRC Press, 7 mai 2019 - 648 pages The Restless Universe: Applications of Gravitational N-Body Dynamics to Planetary Stellar and Galactic Systems stimulates the cross-fertilization of ideas, methods, and applications among the different communities who work in the gravitational N-body problem arena, across diverse fields of astrophysics. The chapters and topics cover three broad the |
