摘要
We address the problem of the opposite asymmetry of low-frequency p-mode line profiles observed in intensity and velocity measurements. We use a simple model to illustrate that this feature can be explained by including a contribution from the stochastic excitation velocity field to the non-resonant background in the Doppler measurements.
