DESCRIPTION:The theory of a complex scalar field minimally coupled to grav
 ity allows for amusing stationary configurations that defy common intuitio
 n built upon our knowledge of more conservative compact objects. Upon rota
 tion\, the topology of the scalar field changes and the solution possesses
  an offcenter distribution of energy density. In turn\, the metric potenti
 als behave nonmotonically with increasing radial coordinate\, deviating co
 nsiderably from external Kerr. In this talk we shall explore the spacetime
  structure of rotating boson stars (BSs) and Kerr black holes with scalar 
 hair (KBHsSH) and address peculiar properties of circular orbits on their 
 equatorial plane\, as well as some astrophysical implications to accretion
  discs and inspirals. Furthermore\, by attempting a fluid description of t
 he complex scalar field\, we will unveil a strange connection between a BS
  co-moving observer and the synchronization condition for KBHsH.
