Asteroseismology from MUSICOS multi-site campaigns

For the MUSICOS international project (MUlti-SIte COntinuous Spectroscopy), the instrument concept and multi-site operational constraints for microvariability and asteroseismology are discussed. Operations and results from previous MUSICOS international campaigns in 1989, 1992, 1994, 1996 involving Pic du Midi, Haute-Provence, South Africa, La Palma, Kitt Peak, ESO La Silla, Hawaii, Anglo-Australian, Xinglong and other observatories are presented. Some MUSICOS asteroseismology highlights on micro-variability and non-radial pulsations on He, delta Scuti, O and B, gamma Dor variables are reviewed. Perspectives for solar-type asteroseismology with multi-site networks in support to space asteroseismology missions such as COROT, are discussed. (C) 1999 COSPAR. Published by Elsevier Science Ltd.
