Abstract The problem relating to the small-amplitude free capillary oscillations
of an encapsulated spherical drop is solved theoretically in the framework of
asymptotic methods. Liquids are supposed to be inviscid and immiscible. The formulas derived are presented for different parameters of the inner and outer liquids,
including densities, thickness of the outer liquid layer, and the surface and interfacial tension coefficients. The frequencies of oscillation of the encapsulated drop
are studied in relation to several “modes” which can effectively be determined in
experiments by photo and video analysis. The results are presented in terms of
