Abstract (from CDS):

Establishing relations between global stellar parameters and asteroseismic quantities can help improve our understanding of stellar astrophysics and facilitate the interpretation of observations. We present an observed relation between the large frequency separation, Δν, and the frequency of maximum power, νmax. We find that Δν ∝ ν0.77max, allowing prediction of Δν to about 15 per cent given νmax. Our result is further supported by established scaling relations for Δν and νmax and by extended stellar model calculations, which confirm that Δν can be estimated using this relation for basically any star showing solar-like oscillations in the investigated range (0.5 < M/M < 4.0).
