DESCRIPTION:Prof. Igor Tkachev (INR Moscow & CERN)\nAxions belong to one o
 f the most viable dark matter particle candidates currently. Examples of a
 xion-like particles are QCD axions and Fuzzy Dark Matter. I'll show that i
 n such classes of models a significant part of dark matter may consist of 
 Bose-stars. Their condensation\, even from virialized state\,  occurs due
  to universal gravitational interactions and does not require additional a
 ssumptions. After reaching critical mass an axion Bose-star becomes unstab
 le. Subsequent collapse is peculiar\, leading to Bose-nova\, while  black
  hole does not form. I'll also discuss various other astrophysical implica
 tions of axion star existence.
