DESCRIPTION:Speakers: Edoardo Giangrandi (Centre for Physics of the Univer
 sity of Coimbra\, Coimbra\, Portugal)\nWe study an accumulation of asymmet
 ric bosonic dark matter inside neutron stars and its further impact on sta
 r's evolution. We present the conditions at which dark matter particles te
 nd to condensate in a core of the star or create an extended halo. We show
  that dark matter condensed in a core leads to a decrease of the total gra
 vitational mass and tidal deformability compared to a pure baryonic star. 
 In addition\, at some conditions self-gravitating dark matter can collapse
  gravitationally and form a black hole that can destroy the star. We study
  the range of particle mass\, coupling constant and fraction of dark matte
 r inside the neutron star that lead to the formation of a black hole insid
 e a compact star. By imposing an existing astrophysical and gravitational 
 wave constraints we set a new limit on the mass and fraction of dark matte
 r particles.\n\nhttps://indico.bitp.kiev.ua/event/8/contributions/218/
