We develop a self-consistent formulation of a slowly rotating, self-gravitating and dilute Bose-Einstein condensate (BEC) in the Newtonian approximation, with a view to astrophysical applications in the context of dark matter halos. BEC dark matter has attracted attention as an alternative to Cold dark matter (CDM) and Warm dark matter (WDM) for some time now. The BEC is described by the Gross-Pitaevskii-Poisson (GPP) equation with an arbitrary potential allowing for either attractive or repulsive interactions. Employing the variational method, we examine the conditions under which rotating condensates that are stable against gravitational collapse may form in models with attractive and repulsive quartic interactions.
