      abstract     = {We calculate the masses of the resonances D*(s0)(2317) and
                      D-s1(2460) as well as their bottom partners as bound states
                      of a kaon and a D-(*())-and B-(*())-meson, respectively, in
                      unitarized chiral perturbation theory at next-to-leading
                      order. After fixing the parameters in the D*(s0)(2317)
                      channel, the calculated mass for the D-s1(2460) is found in
                      excellent agreement with experiment. The masses for the
                      analogous states with a bottom quark are predicted to be
                      MB*(s0) - (5696 +/- 40) MeV and M-Bs1 - (5742 +/- 40) MeV in
                      reasonable agreement with previous analyses. In particular,
                      we predict M-Bs1-MB*(s0) - 46 +/- 1MeV. We also explore the
                      dependence of the states on the pion and kaon masses. We
                      argue that the kaon mass dependence of a kaonic bound state
                      should be almost linear with slope about unity. Such a
                      dependence is specific to the assumed molecular nature of
                      the states. We suggest to extract the kaon mass dependence
                      of these states from lattice QCD calculations.},
