| Abstract: |
The paper examines the possibilities of using ground-based techniques for observing stars which pulsate in more than one mode. The observational arena for asteroseismology is defined. The techniques to be applied depends on the characteristics of the type of stars to be studied. The important parameters are the period, the semiamplitude, the magnitudes of the objects under consideration, and the number of modes in the pulsation spectra. The Doppler and photometric techniques are described. The shortcomings of ground-based observations and the necessity to observe from space are discussed. Instrumentation based on spectroscopy and classes of variables are given in tabular form, and a simulated amplitude spectrum obtained by a network of 4-m telescopes is illustrated. |
