... INTRODUCTION A detailed analysis of high-accuracy, multi-color light curves of the binary system with an exoplanet HD 209458 [1] demonstrated a discrepancy between the observed limb-darkening coefficients and theoretical values obtained from model stellar atmospheres. ... CONCLUSION We have analyzed multi-color transit light curves of the star­exoplanet binary systems HD 209458 and HD 189733 using the theoretical limb-darkening coefficients of [15] and a quadratic limb-darkening law. ...

... We employ Stokes I and V LSD profiles of the co ol magnetic Ap star CrB, extracted for the elements Ti, Cr, Fe and Ba, to confirm systematic element-toelement differences in the longitudinal field variation of this star. ... 5 Mo deling the phase variations The longitudinal field and equivalent width variations of CrB potentially provide a useful method to probe the surface abundance distributions of this and other slowly-rotating magnetic stars. ...
