Abstract
Since the advent of space asteroseismology, enabled by the CoRoT and Kepler space-craft, solar-like oscillations have appeared to be a common feature of low-mass stars from the main-sequence to the red-giant phases. In this context, scaling relations that relate asteroseismological quantities and stellar parameters are an essential tool in the study a large class of stars. Most of these relations concern the connection between pulsations and turbulent convection. Therefore, a deep investigation of this connection is necessary to obtain insight into the processes underlying mode driving and damping and consequently to improve our knowledge of the scaling relations. This is a key step that will permit us to perform a leap forward in our understanding of stellar interiors.

Notes
- 1.
A Lorentzian profile in the Fourier time domain corresponds to an exponentially damped oscillation in the time domain.
- 2.
A detailed derivation can be found in [61].
- 3.
This characteristic size can be determined from the kinetic E(k) or by default using some prescriptions (for more details, see Sect. 11.5.1 in [60]).
- 4.
Note that mode inertia also scales with the dynamical time scale \(\sqrt{(}GM/R^{3})\) with almost the same dispersion as for the surface gravity.
- 5.
A more sophisticated quasi-adiabatic approach has been proposed by [69]. These authors go beyond the approximation of isothermal atmosphere by taking into account the temperature gradient and the fact that the intensity is measured at constant instantaneous optical depth. Both effects are taken into account by the non-adiabatic pulsation code MAD.
- 6.
This scaling is only valid for sub- and red-giant stars.
