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

On the Force-Freeness of the Photospheric Sunspot Magnetic Fields as Observed from Hinode (SOT/SP)
TL;DR: In this paper, the authors examined the global and local nature of magnetic forces over sunspots and found that the sunspot magnetic fields are not much away from force-free configuration, although they are not completely force free on the photosphere.

TL;DR: The EUV Imaging Spectrometer (EIS) on the Hinode satellite is capable of measuring emission line center positions for Gaussian line profiles to a fraction of a spectral pixel, resulting in relative solar Doppler-shift measurements with an accuracy of a less than a km s(-1) for strong lines as discussed by the authors.

TL;DR: In this article, the authors analyzed the results of a series of nonlinear force free field extrapolations of the pre and post flare period of the X1 flare and confirmed the existence of two flux ropes present within the active region prior to flaring.

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.
