Main Scientific objectives

  • Core extension characterization (freqsolar-type, mixed modes in subGiants,…)
  • Surf convprocess (solar-type ampl and width, freq pseudo oscsounding, …)
  • Mass-loss (B SG, hot Be, O stars…)
  • Magneticactiv cycles (solar-likepuls,…)
  • RG scalinglawscalibtration (bright SEISMO field RG,…)
  • Hot O and B Super Giantexploration (essentiallyAnticentre)
  • Solar connexion: (brightenoughsimilar to the Sun)
  • Planets+starsystems: (Bright Stars withplanets)
  • RG population (samplingregions in EXO field)
  • Secondaryones:
  • B, A and F stars instabilitystrip scanning
