Transcript of Time-Distance Helioseismology of the Deep Interior T.L. Duvall Jr. (NASA/GSFC)
Points to cover:
• Magnetic field measurements near convection zone bottom
• Deep flow measurements: surprise! : noise correlated from day to day
• Measuring travel times from convection simulations: how large a signal should there be?
Looking at whether near-surface flows can cause day to day
correlations
• Near-surface flows as shown by the f-mode divergence signal. Overlaid in green is the annulus used for detection of deep flows.
