In this review we give an overview about the current state-of-knowledge of the magnetic field
in sunspots from an observational point of view. We start by offering a brief description of …

Abstract Study Analysis Group 21 (SAG21) of NASA's Exoplanet Exploration Program
Analysis Group was organized to study the effect of stellar contamination on space-based …

The heating of the solar chromosphere and corona is a long-standing puzzle in solar
physics. Hinode observations show the ubiquitous presence of chromospheric anemone jets …

Partially ionized plasmas are found across the Universe in many different astrophysical
environments. They constitute an essential ingredient of the solar atmosphere, molecular …

The Sunrise balloon-borne solar observatory, consisting of a 1 m aperture telescope that
provides a stabilized image to a UV filter imager and an imaging vector polarimeter, carried …

Abstract The Atacama Large Millimeter/submillimeter Array (ALMA) is a new powerful tool for
observing the Sun at high spatial, temporal, and spectral resolution. These capabilities can …

Hinode is Japan's third solar mission following Hinotori (1981–1982) and Yohkoh (1991–
2001): it was launched on 2006 September 22 and is in operation currently. Hinode carries …

Hinode discovered a beautiful giant jet with both cool and hot components at the solar limb
on 2007 February 9. Simultaneous observations by the Hinode SOT, XRT, and TRACE 195 …

Solid evidence of magnetic reconnection is rarely reported within sunspots, the darkest
regions with the strongest magnetic fields and lowest temperatures in the solar atmosphere …

The Sun's outer coronal layer exists at a temperature of millions of kelvins, much hotter than
the solar surface we observe. How this high temperature is maintained and what energy …
