  1. Dark energy accretion onto black holes Vyacheslav Dokuchaev Institute for Nuclear Research of the Russian Academy of Sciences, Moscow La Thuile 2006

  2. Dark Energy? Cosmological constant Λ (vacuum energy) or Quintessence (ultra-light field, inflaton) or Geometrical DE,…

  3. Results: • Solution for a stationary accretion of the relativistic perfect fluid with an equation of state p(ρ) onto the Schwarzschild black hole is presented. • Accretion of phantom energy (ρ+p<0) is accompanied by the gradual decrease of the black hole mass. • Masses of all black holes tend to zero in the phantom energy universe approaching to the Big Rip. See for details:gr-qc/0402089, 0503068 astro-ph/0505618
