Red Giant Seismology
S. Frandsen et al.

Abstract

Asteroseismology of Red Giants has taken a free ride on space missions that really had exoplanets as the major funding reason ({\em Kepler and K2}). The time series of intensity variations for Red Giants have been extraordinary and the results are stunning. TESS will soon provide more of the same kind.
But, can we expect to continue relying on exoplanet missions as collaborators?
From the ground it has been shown (the SONG network), that with a dedicated network of telescopes with state of the art high resolution spectrographs time series of Doppler measurement can give similar high quality power spectra as the space missions.
Ground-based observations still offer possibilities that lead to new information not available from data from space. An example is the advantage presented by the lower intrinsic stellar noise in power spectra of Doppler measurements compared to intensity measurements.
I will discuss a small set of cases, where we can make progress without the need to go to space.
