Detection of Travel Time Anisotropy from Subsurface Horizontal Magnetic Fields
John T. Stefan, Alexander G. Kosovichev
A time-distance measurement technique is derived to isolate phase travel time anisotropy caused by subsurface horizontal magnetic fields, and a method which uses the measured aniso…
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…
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…
Estimation of Key Sunquake Parameters through Hydrodynamic Modeling and Cross-Correlation Analysis
John T. Stefan, Alexander G. Kosovichev
Sunquakes are one of the more distinct secondary phenomena related to solar flares, where energy deposition in the lower layers of the Sun's atmosphere excites acoustic waves easil…
