The Sunspot Solar Observatory Data Archive: Continuing Operations at the Dunn Solar Telescope
Sean G. Sellers, Juie Shetye, Damian J. Christian +9
The Sunspot Solar Observatory Data Archive (SSODA) stores data acquired with the suite of instruments at the Richard B. Dunn Solar Telescope (DST) from February 2018 to the present…
Helioseismology over the solar cycle
M. J. Thompson
Helioseismology has produced unprecedented measurements of the Sun's internal structure and dynamics over the past 25 years. Much of this work has been based on global helioseismol…
Helioseismology of Sunspots: A Case Study of NOAA Region 9787
L. Gizon, H. Schunker, C. S. Baldner +12
Various methods of helioseismology are used to study the subsurface properties of the sunspot in NOAA Active Region 9787. This sunspot was chosen because it is axisymmetric, shows…
Outstanding problems in local helioseismology
L. Gizon, M. J. Thompson
Time-distance helioseismology and related techniques show great promise for probing the structure and dynamics of the subphotospheric layers of the Sun. Indeed time-distance helios…
Modeling the Subsurface Structure of Sunspots
H. Moradi, C. Baldner, A. C. Birch +19
While sunspots are easily observed at the solar surface, determining their subsurface structure is not trivial. There are two main hypotheses for the subsurface structure of sunspo…
Sensitivity of time-distance helioseismic measurements to spatial variation of oscillation amplitudes I. Observations and a numerical model
S. P. Rajaguru, A. C. Birch, T. L. Duvall +2
It is well known that the observed amplitude of solar oscillations is lower in sunspots than in quiet regions of the Sun. We show that this local reduction in oscillation amplitude…
