Descripción
Observational results concerning possible changes in the granulation of Main Sequence stars were found by analysing their seismic power spectra obtained from photometric microvariability. We analysed as many as 178 stars with spectral types F, G, K, and M observed for 54 days. We present evidence of changes in the lifetime and contrast of the granulation, which both increase from F to M stars, although within the limit of resolution.
