Oscillatory convective modes in red giants: A possible explanation of the long secondary periods
We discuss properties of oscillatory convective modes in low-mass red giants, and compare them with observed properties of the long secondary periods (LSPs) of semiregular red giant variables. Oscillatory convective modes are very non-adiabatic g− modes and they are present in luminous stars, such as red giants with log L/L⊙ ≳ 3. Finite amplitudes for these modes are confined to the outermost non-adiabatic layers, where the radiative energy flux is more important than the convective energy...[Show more]
