A Probabilistic Framework for Incorporating Helioseismic Far-Side Active Regions into SFT Models

Bibhuti Kumar Jha, Lisa A. Upton, K. D. Leka +5

Surface Flux Transport (SFT) models are routinely used to model the Sun's photospheric magnetic field and provide inner boundary conditions for coronal and heliospheric models, yet…

Solar-cycle variations in meridional flows and rotational shear within the Sun's near-surface shear layer

Anisha Sen, S. P. Rajaguru, Abhinav Govindan Iyer +3

Using solar-cycle long helioseismic measurements of meridional and zonal flows in the near-surface shear layer (NSSL) of the Sun, we study their spatio-temporal variations and conn…

Removal Of Active Region Inflows Reveals a Weak Solar Cycle Scale Trend In Near-surface Meridional Flow

Sushant S. Mahajan, Xudong Sun, Junwei Zhao

Using time-distance local helioseismology flow maps within 1 Mm of the solar photosphere, we detect inflows toward activity belts that contribute to solar cycle scale variations in…

Solar wave-field simulation for testing prospects of helioseismic measurements of deep meridional flows

Thomas Hartlep, Junwei Zhao, Alexander G. Kosovichev +1

The meridional flow in the Sun is an axisymmetric flow that is generally poleward directed at the surface, and is presumed to be of fundamental importance in the generation and tra…

Time--Distance Helioseismology Data Analysis Pipeline for Helioseismic and Magnetic Imager onboard Solar Dynamics Observatory (SDO/HMI) and Its Initial Results

J. Zhao, S. Couvidat, R. S. Bogart +6

The Helioseismic and Magnetic Imager onboard the Solar Dynamics Observatory (SDO/HMI) provides continuous full-disk observations of solar oscillations. We develop a data-analysis p…

Local helioseismology of sunspot regions: comparison of ring-diagram and time-distance results

A. G. Kosovichev, S. Basu, R. Bogart +10

Local helioseismology provides unique information about the subsurface structure and dynamics of sunspots and active regions. However, because of complexity of sunspot regions loca…
