Description
Aims:The detection and measurement of acoustic modes on the giant
planets of the solar system is of great interest for the study of the
internal structure and evolution of the giant planets, as well as the
study of the solar system formation. Such observations require a
dedicated instrument and observing procedure. Methods: We
describe the principle and the performance of an instrument dedicated to
seismology of giant planets. In this first paper, we describe the
principle and the optical scheme, and derive the theoretical
performances. As for the Sun, it is possible to measure modes with
spatial resolution, but a larger collecting area is necessary. As for
asteroseismology in general, continuity in the observation is also
required. Results: From results obtained at the laboratory, we
derive the actual performance of the instrument and estimate its
capabilities in network observations. Conclusions: We demonstrate
that the proposed instrument and strategy is adapted for the seismology
of giant planets. In a second paper, we will present the first data set
obtained with it, explain the data reduction procedure, and present
preliminary results.
