Origin of Coronal Extreme Ultraviolet Shockwaves without a Coronal Mass Ejection Event
Robert Bush, John Stefan, Alexander Kosovichev
A leading theory of sunquake generation involves flare-accelerated particles depositing energy into the photosphere. Simulations of sunquake excitation suggest co-excitation with w…
An Acoustic Model for Sunquakes Unifying the Solar Interior and Atmosphere
John Stefan, Alexander Kosovichev
One of the leading hypotheses for sunquake generation suggests that flare-accelerated particles originating from the reconnection site in the corona travel down to the chromosphere…
Operational and Exploration Requirements and Research Capabilities for SEP Environment Monitoring and Forecasting
Viacheslav Sadykov, Petrus Martens, Dustin Kempton +15
Mitigating risks posed by solar energetic particles (SEPs) to operations and exploration in space and Earth's atmosphere motivates the development of advanced, synergistic approach…
Structure and Dynamics of the Sun's Interior Revealed by Helioseismic and Magnetic Imager
Alexander Kosovichev, Sarbani Basu, Yuto Bekki +43
High-resolution helioseismology observations with the Helioseismic and Magnetic Imager (HMI) onboard Solar Dynamics Observatory (SDO) provide a unique three-dimensional view of the…
Solar Meridional Flow in the Shallow Interior during the Rising Phase of Cycle 24
Junwei Zhao, A. G. Kosovichev, R. S. Bogart
Solar subsurface zonal and meridional-flow profiles during the rising phase of solar cycle 24 are studied using time-distance helioseismology technique. The faster zonal bands in t…
High Resolution Observations of Chromospheric Jets in Sunspot Umbra
V. Yurchyshyn, V. Abramenko, S. Kosovichev +1
Recent observations of sunspot's umbra suggested that it may be finely structured at a sub-arcsecond scale representing a mix of hot and cool plasma elements. In this study we repo…
