Coronal Active Region Modelling Based on SDO Data

Extended MHD modeling of the steady solar corona and the solar wind

The history and present state of large-scale magnetohydrodynamic modeling of the solar corona and the solar wind with steady or quasi-steady coronal physics is reviewed and the latest, state-of-the art models are discussed.

Commentary: Discovery of the Sun's million-degree hot corona

Discovery of the Sun's million-degree hot corona

As time goes by, discoveries become common knowledge, and often the person who first changed a paradigm gets forgotten. One such case is the discovery that the Sun’s corona is a million degrees hot –

Knowing Science

Knowing Science presents an epistemology of science that rejects empiricism and gives a central place to the concept of knowledge. Science aims at knowledge and progresses when it adds to the stock

The Solar X-ray Corona

The X-ray emission from the Sun reveals a very dynamic hot atmosphere, the corona, which is characterized by a complex morphology and broad range of timescales of variability and spatial structuring.

Solar Kaluza-Klein axion search with NEWS-G

Kaluza-Klein (KK) axions appear in theories with extra dimensions as higher mass, significantly shorter lifetime, excitations of the Peccei-Quinn axion. When produced in the Sun, they would remain

EUV Beam-Foil Spectra of Titanium, Iron, Nickel, and Copper

Beam–foil spectroscopy offers the efficient excitation of the spectra of a single element as well as time-resolved observation. Extreme-ultraviolet (EUV) beam–foil survey and detail spectra of Ti,

A confluence of circumstances led to astronomers proposing three new elements in the 1860s (nebulium 1864, helium 1868, and coronium 1869) though the names came a bit later. Two of these proved to be

Forbidden Lines of Fe VII in the Spectrum of Nova RR Pictoris (1925)

THE bright line spectrum of Nova RR Pictoris (1925) is characterized in the later stages by a group of lines in the visible region, of which the most prominent, λ 5723 and λ 6087, form with Hα and λ
