Radiative steering of warp shells
An T. Le
We construct exact timelike junctions between compact flat cavities and a Kinnersley photon-rocket exterior. The shells satisfy the strict surface dominant energy condition and ste…

Relativistic elastic shells: material support and cavity geometry
An T. Le
We derive the source moments that determine the leading tidal field and rotational clock shift inside a finite-thickness relativistic elastic shell. In weak gravity and slow rotati…

Rarity of rocket-driven Penrose extraction in Kerr spacetime
An T. Le
We study rocket-driven Penrose extraction in the test-particle limit on a fixed Kerr background for equatorial prograde flybys under explicit steering prescriptions. A spacecraft e…
