  We present a mechanism for catalyzed vacuum bubble production obtained by
combining moduli stabilization with a generalized attractor phenomenon in which
moduli are sourced by compact objects. This leads straightforwardly to a class
of examples in which the Hawking decay process for black holes unveils a bubble
of a different vacuum from the ambient one, generalizing the new endpoint for
Hawking evaporation discovered recently by Horowitz. Catalyzed vacuum bubble
production can occur for both charged and uncharged bodies, including
Schwarzschild black holes for which massive particles produced in the Hawking
process can trigger vacuum decay. We briefly discuss applications of this
process to the population and stability of metastable vacua.
