Helioseismic Modeling of Background Flows
Andrey M. Stejko, Alexander G. Kosovichev, Nagi N. Mansour
We present a 3-dimensional (3D) numerical solver of the linearized compressible Euler equations (GALE -- Global Acoustic Linearized Euler), used to model acoustic oscillations thro…
Evolution of Subsurface Zonal and Meridional Flows in Solar Cycle 24 from Helioseismological Data
Alexander V. Getling, Alexander G. Kosovichev, Junwei Zhao
The results of determinations of the azimuthal and meridional velocities by time-distance helioseismology from Helioseismic and Magnetic Imager (HMI) onboard Solar Dynamics Observa…
Analysis of Time-Distance Helioseismology for Detection of Emerging Active Regions
John T. Stefan, Alexander G. Kosovichev, Andrey M. Stejko
A time-distance helioseismic technique, similar to the one used by Ilonidis et al (2011), is applied to two independent numerical models of subsurface sound-speed perturbations to…
Connecting Atmospheric Properties and Synthetic Emission of Shock Waves Using 3D RMHD Simulations of Quiet Sun
Viacheslav M. Sadykov, Irina N. Kitiashvili, Alexander G. Kosovichev +1
We analyze the evolution of shock waves in high-resolution 3D radiative MHD simulations of the quiet Sun and their synthetic emission characteristics. The simulations model the dyn…
Machine Learning in Heliophysics and Space Weather Forecasting: A White Paper of Findings and Recommendations
Gelu Nita, Manolis Georgoulis, Irina Kitiashvili +38
The authors of this white paper met on 16-17 January 2020 at the New Jersey Institute of Technology, Newark, NJ, for a 2-day workshop that brought together a group of heliophysicis…
Machine-learning approach to identification of coronal holes in solar disk images and synoptic maps
Egor Illarionov, Alexander Kosovichev, Andrey Tlatov
Identification of solar coronal holes (CHs) provides information both for operational space weather forecasting and long-term investigation of solar activity. Source data for the f…
