| contents | We review solar studies using AIA, HMI, and EVE data from the SDO spacecraft that revolutionized our physical understanding of the Sun. The relevant SDO studies cover the entire 15-year lifetime of SDO, from 2010 May 1 to 2025 May 1. The discussed phenomena and their physical interpretations include (in chronological order):
(1) MHD Waves and Oscillations (AIA, HMI);
(2) Propagating MHD Waves (AIA);
(3) Coronal Loop Cross-Sectional Temperatures (AIA);
(4) Size Distributions of Solar Flare Parameters (AIA);
(5) Spatio-Temporal Evolution and Diffusion (AIA);
(6) The Rosner-Tucker-Vaiana (RTV) Scaling Law (AIA);
(7) The Fractal-Diffusive Self-Organized Criticality Model (AIA);
(8) Automated Temperature and Emission Measure Maps (AIA);
(9) Automated Pattern Recognition Codes (AIA);
(10) Kelvin-Helmholtz Instability in Reconnetion Outflows (AIA);
(11) Hydrodstatics of Coronal Loops (AIA);
(12) Magnetic Energy Dissipation (HMI);
(13) Global Energetics of Solar Flares (AIA). |
