Abstract: Light scalar fields are the essence of many well-motivated theories beyond the Standard Model of particle physics. In this thesis, we study the rich phenomenology of the interplay between these fields and the finite baryon density present in astrophysical environments such as stars and supernovae. The emerging phenomena range from changes in QCD axion couplings to phase transitions from stars to changing the stellar landscape. Compatibility with observations allows us to put stringent constraints on such models.
