Abstract

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).

太阳动力学观测站如何促进了我们对太阳的物理认识

我们使用来自SDO航天器的AIA、HMI和EVE数据来回顾太阳研究，这些数据提高了我们对太阳的物理认识。相关的SDO研究涵盖了SDO的整个15年生命周期，从2010年5月1日到2025年5月1日。所讨论的现象及其物理解释包括（按时间顺序）：(1)MHD波和振荡（AIA， HMI）；(2)传播MHD波（AIA）；(3)日冕环截面温度（AIA）；(4)太阳耀斑参数（AIA）的尺寸分布；(5)时空演化与扩散（AIA）；(6) Rosner-Tucker-Vaiana （RTV）标度定律（AIA）；(7)分形扩散自组织临界模型（AIA）；(8)自动温度和排放测量图（AIA）；(9)自动模式识别代码（AIA）；（10）重连接流出（AIA）中的Kelvin-Helmholtz不稳定性；（11）日冕环流体静力学；（12）磁能耗散（HMI）；（13）太阳耀斑全球能量学（AIA）。

期刊介绍： Solar Physics was founded in 1967 and is the principal journal for the publication of the results of fundamental research on the Sun. The journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution to the outer corona and solar wind in interplanetary space. Papers on solar-terrestrial physics and on stellar research are also published when their results have a direct bearing on our understanding of the Sun.
