Commentary: Discovery of the Sun's million-degree hot corona
Exploring the diagnostic value of He I D3 in the solar chromosphere
This thesis focusses on observations of the He I D3 line at 5876 Å in the solar chromosphere. The He I D3 line is part of the triplet system of neutral helium (as is the more commonly observed He I
The response of the corona to different spatial distributions of heat input
Explaining the existence of the million degree corona on top of the much cooler Solar surface has provided scientist with a challenge for a several decades. It is not possible for a cooler object to
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 –
