Helioseismology, Time Distance, Solar P-Modes Lifetime

Scientific paper

We use the method of time-distance analysis to measure lifetimes of solar p-modes in the range l=100-600 with data taken with the Taiwan Oscillation Network (TON). The lifetimes of p-modes are determined by the changes in the amplitude and width of the cross-correlation function of a wave packet with number of skips. The amplitude of cross-correlation function decreases pontentially with the number of skips as in the previous study Chou et al.(2001). This decrease has been interpreted as the effect of the finite p-mode lifetime. In this study, we find that the width of cross-correlation function increases with the number of skips. We interpret this phenomenon as the effect of the dispersion of the wave packet. We include this effect in the determination of lifetime of the wave packet. We also study the change in lifetime between solar minimum and maximum.
