Instability of rotating Bose stars
A. S. Dmitriev, D. G. Levkov, A. G. Panin +2
Light bosonic (axion-like) dark matter may form Bose stars - clumps of nonrelativistic Bose-Einstein condensate supported by self-gravity. We study rotating Bose stars composed of…

Radio-emission of axion stars
D. G. Levkov, A. G. Panin, I. I. Tkachev
We study parametric instability of compact axion dark matter structures decaying to radiophotons. Corresponding objects - Bose (axion) stars, their clusters, and clouds of diffuse…

Gravitational Bose-Einstein condensation in the kinetic regime
D. G. Levkov, A. G. Panin, I. I. Tkachev
We study Bose-Einstein condensation and formation of Bose stars in the virialized dark matter halos/miniclusters by universal gravitational interactions. We prove that this phenome…
