We present a detailed study of the temperature dependence of the conde
nsate and noncondensate density profiles of a Bose-condensed gas in a
parabolic trap. These quantities are calculated self-consistently usin
g the Hartree-Fock-Bogoliubov equations within the Popov approximation
. Below the Bose-Einstein transition the excitation frequencies have a
relatively weak temperature dependence even though the condensate is
strongly depleted. As the condensate density goes to zero through the
transition, the excitation frequencies are strongly affected and appro
ach the frequencies of a noninteracting trapped gas in the high temper
ature limit.
