Lattice Melting and Rotation in Perpetually Pulsating Equilibria
C. Pichon, D. Lynden-Bell, J. Pichon +1
Systems whose potential energies consists of pieces that scale as r^-2 together with pieces that scale as r^2, show no violent relaxation to Virial equilibrium but may pulsate at c…
Gravitational energy in stationary spacetimes
Joseph Katz, Donald Lynden-Bell, Jiri Bicak
Static observers remain on Killing-vector world lines and measure the rest-mass+kinetic energies of particles moving past them, and the flux of that mechanical energy through space…
An Orphan in the "Field of Streams"
V. Belokurov, N. W. Evans, M. J. Irwin +19
We use Sloan Digital Sky Survey Data Release 5 photometry and spectroscopy to study a tidal stream that extends over 50 degrees in the North Galactic Cap. From the analysis of the…
Hamilton's Eccentricity Vector Generalised to Newton Wonders
D. Lynden-Bell
The vectorial velocity is given as a function of the position of a particle in orbit when a Newtonian central force is supplemented by an inverse cubic force as in Newton's theorem…
Magnetic Jets from Swirling Disks
D. Lynden-Bell
A broad swathe of astrophysical phenomena, ranging from tubular planetary nebulae through Herbig-Haro objects, radio-galaxy and quasar emissions to gamma-ray bursts and perhaps hig…
