Formation of dark energy stars

Understand

Dark energy stars are finite size astrophysical objects with an interior equation of state typical of dark energy.

• Examples are self-gravitating false vacuum bubbles, vacuum non-singular black holes, and gravastars.
• We present a time-dependent solution of Einstein's field equations that describes the collapse of a spherical system from an initial state of positive pressure to a final state with a dark energy core.
• Our solution has no singularities, no event horizons, and does not violate the weak or null energy conditions.
