Vemury, S.K., and R. Stothers, 1977: Nonradial pulsational instability of massive stars. Astrophys. J., 214, 809-811, doi:10.1086/155310.

Pulsational eigenfrequencies and stability coefficients of the lowest modes of nonradial quadrupole (l=2) oscillation have been obtained for chemically homogeneous stellar models constructed with Carson's (1976) radiative opacities. Instability is found to develop as a result of the same operation of the kappa-mechanism in the CNO ionization zone and at nearly the same stellar masses as was the case for the radial (l=0) modes studied previously. A survey of the l=5 modes indicates that the instability gradually declines with increasing degree of the spherical harmonics.
