Novel very-high-frequency quasi-periodic oscillations of compact, non-singular objects
Jens Boos, Felix Wunsch
We report on a novel set of very-high-frequency quasi-periodic oscillations (VHFQPO's) in the context of compact, non-singular horizonless objects. Focussing on the static, spheric…

`Translation invariant' black hole: autoparallels and complete integrability
Jens Boos
We consider the autoparallel motion of test bodies in static, spherically symmetric spacetimes with torsion. We prove complete integrability of such motion for a wide range of off-…

Torsion in two dimensions: autoparallels, symmetries, and applications to black holes
Jens Boos
We explore spacetime torsion in a two-dimensional setting, wherein it corresponds to a vector field. Without invoking field equations of a particular gravitational theory, we devel…
