Solar Subsurface Flows from Helioseismology: Problems and Prospects

Helioseismology Workshop

July 21 - 23, 2014, Stanford, CA

Program outline

This is the current program for the workshop. The list of speakers and the order should not be considered final.

Monday, July 21: Understanding and Mitigating Systematic Errors

Session 1: Distortions, position angles, and 24-hour periods - problems with the raw data

Chair: Rick Bogart

This session is devoted to understanding issues in the data used for helioseismic studies.


Session 2a: The 'center-to-limb' effect and its effect on flows

Chair: Junwei Zhao

Helioseismic measurements of flows appear to suffer from an large systematic error that depends on the heliocentric angle. This effect is particularly important in the measurement of meridional flows, as the magnitude of the error can be larger than the signal. The first half of this session will focus on characterizing and understanding this error.


Session 2b: Measuring meridional flows

Chair: Junwei Zhao

The second half of this session will focus on strategies for accurately measuring meridional flows.


Tuesday, July 22: Simulations, Inversions, and Results

Session 2 (continued):

Session 1 (continued):

Session 3: Synthetic data and validation of inversions

Chair: Jason Jackiewicz

Simulation data can be used to understand the more complicated processes that influence our observations. This session will include both descriptions of available data and discussions of work that has been done using these data.


Session 4: Science results

Chair: Charles Baldner

Wednesday, July 23: Unstructured discussion and breakouts

Participants are free to form their own smaller discussion groups. A number of small meeting rooms are available. Douglas Gough will give a talk to conclude the workshop in the afternoon.
