2D-models of rapidly rotating early-type stars: the ESTER project
Francisco Espinosa Lara and Michel Rieutord


Many stars where numerous oscillation frequencies are observed, are rapidly rotating. This is the case of several CoRoT targets like HD 181555 showing hundreds of modes. The identification of observed frequencies and their interpretation in terms of fundamental parameters of the stars require the use of two-dimensional models where the centrifugal distortion of the star and the induced baroclinic flows are fully taken into account. We present here the first self-consistent two-dimensional models of such stars and their comparison to a set of nearby fast rotating early-type stars that have been observed with infra-red or optical interferometry, including the delta Scuti star alpha Ophiuchi.
