1. The shallow minimum is the result of a first overtone pulsation. 2. Confirmed first overtone pulsators include BG Crucis and BP Circini. 3. The majority of these are thought to be first overtone ( e . g. 4. When two quanta are absorbed the first overtone is excited, and so on to higher overtones. 5. EP were recording their first overtones " Thrash Metal " Malaysia is the first released to the market. 6. Cepheid variables may pulsate in a fundamental mode, the first overtone , or rarely a mixed mode. 7. The second harmonic is the first overtone , the third harmonic is the second overtone, and so on. 8. They are core helium-burning giants that oscillate in one or both of their fundamental mode or first overtone . 9. The lowest one in frequency is the fundamental frequency, and the next highest natural frequency is the first overtone . 10. In reality, vibrations are anharmonic and the first overtone has a frequency that is slightly lower than twice that of the fundamental.
