The Heine-Stieltjes correspondence is extended and applied to solve Bethe ansatz equations of the Gaudin-Richardson models, from which the extended Heine-Stieltjes polynomial approach to these models is proposed. As examples for the application of this approach, exact solutions of the standard two-site Bose-Hubbard model and the standard pairing model for nuclei are formulated from the corresponding polynomials. © Published under licence by IOP Publishing Ltd.
