TLDR
The Hinode satellite as discussed by the authors is the successor to the Yohkoh mission, which aims to understand how magnetic energy gets transferred from the photosphere to the upper atmosphere and results in explosive energy releases.Abstract:
The Hinode satellite (formerly Solar-B) of the Japan Aerospace Exploration Agency’s Institute of Space and Astronautical Science (ISAS/JAXA) was successfully launched in September 2006. As the successor to the Yohkoh mission, it aims to understand how magnetic energy gets transferred from the photosphere to the upper atmosphere and results in explosive energy releases. Hinode is an observatory style mission, with all the instruments being designed and built to work together to address the science aims. There are three instruments onboard: the Solar Optical Telescope (SOT), the EUV Imaging Spectrometer (EIS), and the X-Ray Telescope (XRT). This paper provides an overview of the mission, detailing the satellite, the scientific payload, and operations. It will conclude with discussions on how the international science community can participate in the analysis of the mission data.read more

TL;DR: In this paper, the electron density and temperature distributions of the coronal emission have been determined using emission line intensity ratios, and the highest temperature and electron density values are found to be located in the core of the active region, with a peak electron number density value of 1.9 × 10 10 cm −3 measured using the Fe XII 186.887 A to 192.394 A line intensity ratio.

Evolution of the flaring active region NOAA 10540 as a sequence of nonlinear force-free field extrapolations
TL;DR: In this paper, a nonlinear force-free field model was used to estimate the energy content of the 3D coronal field, as well as an upper limit for its free magnetic energy.

TL;DR: In this article, the authors presented the first joint observation of a micro-flare with NuSTAR and Hinode/XRT on 2015 April 29 at ~11:29 UT, showing the heating of material to several million Kelvin, observed in soft X-rays with Hinode XRT, and was faintly visible in the extreme ultraviolet with SDO/AIA.

A loop-top hard X-ray source in a compact solar flare as evidence for magnetic reconnection
TL;DR: In this paper, the authors identify the reconnection region as the site of particle acceleration, suggesting that the basic physics of the magnetic reconnection process may be common to both types of flares.

Sigmoidal morphology and eruptive solar activity
TL;DR: In this paper, the authors studied the Yohkoh Soft X-Ray Telescope video movie for 1993 and 1997 and found that regions are significantly more likely to be eruptive if they are either sigmoidal or large.

Statistical Study of Solar X-Ray Jets Observed with the YOHKOH Soft X-Ray Telescope
TL;DR: In this article, a statistical study of 100 X-ray jets, found from the database of full Sun images taken with the Soft X-Ray Telescope (SXT) aboard Yohkoh during the period between November 1991 and April 1992, was conducted.
