We study the spatial distribution of particles in two-component Bose–Einstein condensates containing vortices. We show that the form in which the species are arranged inside the condensate may be easily understood using simple approximations. We obtain expressions for the location of particular points which are useful for describing the density of particles in two limiting situations, using either the Thomas–Fermi approximation or a low-dilution approximation. A discussion about the shape of vortex cores is also included.
