Abstract
A theoretical description of shell structure for charged particles in a harmonic trap is explored at strong coupling conditions of = 50 and 100. The theory is based on an extension of the hypernetted chain approximation to confined systems plus a phenomenological representation of associated bridge functions. Predictions are compared to corresponding Monte Carlo simulations and quantitative agreement for the radial density profile is obtained.
