We study pion and kaon condensation using three-flavor chiral perturbationtheory at finite isospin and strangeness quark chemical potentials {\mu}I and{\mu}S . The phase diagram consists of a vacuum phase and three distinct Bosecondensed phases with condensates of charged pions as well as charged andneutral kaons. Adding electromagnetic interactions, a phase with a chargedcondensate becomes a Higgs phase and the resulting phase diagram is modifieddue to the electromagnetic mass splittings of the mesons. The results for thepion-condensed phase are applied to calculate mass-radius relation of pionstars. Local electric charge neutrality is imposed by adding electrons, muonstogether with their neutrionos. Finally, we compare our results for themass-radius relations with those from recent lattice simulations, and find verygood agreement.
