The Evolution of a Horizontal Branch Population II Star with Total Mass $0.63enspace M_odot
The theoretical evolution of a horizontal branch star of Population II is followed through the helium burning in the core phase and is compared with the results given by other investigators. The influence of different physics and interpolation schemes in the opacity tables is discussed. Some thought...

| Zusammenfassung: | The theoretical evolution of a horizontal branch star of Population II is followed through the helium burning in the core phase and is compared with the results given by other investigators. The influence of different physics and interpolation schemes in the opacity tables is discussed. Some thoughts are given on the explanation of the erratic period variations observed in some of the RR Lyrae variables in the globular clusters. |
