The solar chromosphere forms a crucial, yet complex and until recently poorly understood,
interface between the solar photosphere and the heliosphere.▪ Advances in high-resolution …

Newly available high-resolution imaging of solar radio emission at many closely spaced
frequencies and times provides new physical insight into the processes, structure, and …

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 …

Incoherent solar radio radiation comes from the free-free, gyroresonance, and
gyrosynchrotron emission mechanisms. Free-free is primarily produced from Coulomb …

The microwave spectrum contains valuable information about solar flares. Yet, the present
spectral coverage is far from complete and broad data gaps exist above 20 GHz. Here we …

Abstract The Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope has
commenced science observations of the Sun starting in late 2016. Since the Sun is much …

Context. Numerical simulations of the solar chromosphere predict a diverse thermal
structure with both hot and cool regions. Observations of plage regions in particular typically …

Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely,
from a close distance, in and out of the ecliptic. The ultimate goal is to understand how the …

Observations at (sub-) millimeter wavelengths offer a complementary perspective on our
Sun and other stars, offering significant insights into both the thermal and magnetic …

In December 2016, the Atacama Large Millimeter/submillimeter Array (ALMA) carried out the
first regular observations of the Sun. These early observations and the reduction of the …
