## 2. Normal modes of a starThe formalism below is parallel to that of Beiki and Sobouti (1990)
who studied excitation of the oscillation of a binary member by its
companion. Consider a non rotating spherical star in hydrostatic
equilibrium. Let a mass element at where All terms in Eq. (1) are expressed in terms of the vector field . The second equality in this equation is the definition for the operator whose properties will be discussed shortly. © European Southern Observatory (ESO) 1997 Online publication: June 30, 1998 |
