Rotation of inertial frames by angular momentum of matter and waves
William Barker, Tomáš Ledvinka, Donald Lynden-Bell +1
We elucidate the dynamics of a thin spherical material shell with a tangential pressure, using a new approach. This is both simpler than the traditional method of extrinsic curvatu…
Corotating light cylinders and Alfvén waves
K. N. Gourgouliatos, D. Lynden-Bell
Exact relativistic force free fields with cylindrical symmetry are explored. Such fields are generated in the interstellar gas via their connection to pulsar magnetospheres both in…
Are Complex A and the Orphan Stream related?
Shoko Jin, D. Lynden-Bell
We consider the possibility that the Galactic neutral hydrogen stream Complex A and the stellar Orphan stream are related, and use this hypothesis to determine possible distances t…
Simplified Variational Principles for Barotropic Magnetohydrodynamics
Asher Yahalom, Donald Lynden-Bell
Variational principles for magnetohydrodynamics were introduced by previous authors both in Lagrangian and Eulerian form. In this paper we introduce simpler Eulerian variational pr…
Exact Optics: A unification of optical telescope design
D. Lynden-Bell
A perfect focus telescope is one in which all rays parallel to the axis meet at a point and give equal magnification there. It is shown that these two conditions define the shapes…
A spacetime dual to the NUT spacetime
Mohammad Nouri-Zonoz, Naresh Dadhich, D. Lynden-Bell
By decomposing the Riemann curvature into electric and magnetic parts, a duality transformation, which involves interchange of active and passive electric parts, has recently been…
