Instability of radial oscillations of Wolf-Rayet star models

Kırbıyık, Halil
By taking some evolutionary models of an initially 60M ⊙-star, their radial vibrational stabilities have been investigated. These models, evolving with mass loss, are in the advanced stages of their evolution, and burn He in their cores. Calculations have been performed for the first and second harmonics as well as for the fundamental mode; and some of these models were found to be vibrationally unstable in the fundamental mode.
