  This talk is based on work done in collaboration with G.E. Brown and D.-P.
Min on kaon condensation in dense baryonic medium treated in chiral
perturbation theory using heavy-baryon formalism. It contains, in addition to
what was recently published, some new results based on the analysis on kaonic
atoms by Friedman, Gal and Batty and a discussion on a renormalization-group
analysis to meson condensation made together with H.K. Lee and Sin. Negatively
charged kaons are predicted to condense at the critical density $2\lsim
\rho/\rho_0\lsim 4$, in the range to allow all the intriguing new phenomena
predicted by Brown and Bethe to take place in compact star matter.
