Stability of Rotating, Charged Fluids: Generalization of the Hoiland Conditions in Newtonian Non-conductive Case
Kris Schroven, Vladimir Karas, Jiri Horak +2
We study the conditions for stability of electrically charged, non-conductive perfect fluid tori with respect to linear perturbations. To this end we employ Lagrangian perturbation…

The ISCO of charged particles in Reissner-Nordström, Kerr-Newman and Kerr-Sen spacetime
Kris Schroven, Saskia Grunau
In this article we study the innermost stable circular orbit (ISCO) of electrically charged particles in the electrically charged Reissner-Nordström spacetime, the Kerr-Newman spac…

Stability of self-gravitating Bose-Einstein-Condensates
Kris Schroven, Meike List, Claus Lämmerzahl
We study the ground state and the first three radially excited states of a self-gravitating Bose-Einstein- Condensate with respect to the influence of two external parameters, the…
