The Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO)

TLDR
The Atmospheric Imaging Assembly (AIA) as discussed by the authors provides multiple simultaneous high-resolution full-disk images of the corona and transition region up to 0.5 R ⊙ above the solar limb with 1.5-arcsec spatial resolution and 12-second temporal resolution.
Abstract
The Atmospheric Imaging Assembly (AIA) provides multiple simultaneous high-resolution full-disk images of the corona and transition region up to 0.5 R ⊙ above the solar limb with 1.5-arcsec spatial resolution and 12-second temporal resolution. The AIA consists of four telescopes that employ normal-incidence, multilayer-coated optics to provide narrow-band imaging of seven extreme ultraviolet (EUV) band passes centered on specific lines: Fe xviii (94 A), Fe viii, xxi (131 A), Fe ix (171 A), Fe xii, xxiv (193 A), Fe xiv (211 A), He ii (304 A), and Fe xvi (335 A). One telescope observes C iv (near 1600 A) and the nearby continuum (1700 A) and has a filter that observes in the visible to enable coalignment with images from other telescopes. The temperature diagnostics of the EUV emissions cover the range from 6×104 K to 2×107 K. The AIA was launched as a part of NASA’s Solar Dynamics Observatory (SDO) mission on 11 February 2010. AIA will advance our understanding of the mechanisms of solar variability and of how the Sun’s energy is stored and released into the heliosphere and geospace.

Slipping magnetic reconnection of flux-rope structures as a precursor to an eruptive x-class solar flare

TL;DR: The quasi-periodic slipping motion of flux rope structures prior to the onset of an eruptive X-class flare on 2015 March 11, obtained by the Interface Region Imaging Spectrographs (IRIS) and the Solar Dynamics Observatory (SDO) was studied in this paper.

Multi-wavelength Spectral Analysis of Ellerman Bombs Observed by FISS and IRIS

TL;DR: In this paper, a spectral analysis of the EBs simultaneously observed by the Fast Imaging Solar Spectrograph (FISS) and IRIS was performed, showing clear evidence of heating in the lower atmosphere, indicated by the wing enhancement in H$\alpha, Ca II 8542 A and Mg II triplet lines, and also by brightening in the images of 1700 A and 2832 A ultraviolet continuum channels.

Two-dimensional Cellular Automaton Model for the Evolution of Active Region Coronal Plasmas

TL;DR: In this paper, a two-dimensional cellular automaton model for the evolution of coronal loop plasmas is proposed. But the model is based on the idea that coronal loops are made of elementary magnetic strands that are tangled and stressed by the displacement of their footpoints by photospheric motions, which is released in sudden reconnection events or nanoflares that heat the plasma.

CHIANTI - an atomic database for emission lines - I. Wavelengths greater than 50 Å

TL;DR: The CHIANTI database as mentioned in this paper is a set of atomic data and transition probabilities necessary to calculate the emission line spectrum of astrophysical plasmas, including atomic energy levels, atomic radiative data such as wavelengths, weighted oscillator strengths and A values, and electron collisional excitation rates.

The X-Ray Telescope (XRT) for the Hinode Mission

TL;DR: The X-ray Telescope (XRT) of the Hinode mission as mentioned in this paper provides an unprecedented combination of spatial and temporal resolution in solar coronal studies, and the high sensitivity and broad dynamic range of XRT, coupled with the spacecraft's onboard memory capacity and the planned downlink capability, will permit a broad range of solar studies over an extended period of time for targets ranging from quiet Sun to X-flares.
