摘要

We review solar studies using AIA, HMI, and EVE data from the SDO spacecraft that advanced 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 Reconnection Outflows (AIA);

(11) Hydrostatics of Coronal Loops (AIA);

(12) Magnetic Energy Dissipation (HMI);

(13) Global Energetics of Solar Flares (AIA).
