The effects of both elliptical shape and stage of emergence of the coronalloop on the resonant absorption of standing kink oscillations are studied. Todo so, a typical coronal loop is modeled as a zero-beta longitudinallystratified cylindrical magnetic flux tube. We developed the connection formulaefor the resonant absorption of standing transversal oscillations of a coronalloop with an elliptical shape, at various stages of its emergence. Using theconnection formulae, the dispersion relation is derived and solved numericallyto obtain the frequencies and damping rates of the fundamental andfirst-overtone kink modes. Our numerical results show that both the ellipticalshape and stage of emergence of the loop alter the frequencies and dampingrates of the tube as well as the ratio of frequencies of the fundamental andits first-overtone modes. However, the ratio of the oscillation frequency tothe damping rate is not affected by the tube shape and stage of its emergenceand also is independent of the density stratification parameter.
