We review the equation of state of deconfined matter at high densities and study the structure of stellar objects made up of these phases. We highlight the novel features of the latter with particular emphasis in pairing interactions. Although the effects of pairing on the equation of state are thought to be small, we find that color flavor locking and diquark states produce stars that may be in fact much more compact than strange stars. This feature may be relevant in view of some recent observations claiming the existence of exotic and/or deconfined phases in some nearby neutron stars.
