IF “my mathematical result was based upon data among which the principal point at issue was accepted as proved,” it will be easy for you to state what that point is,* and to quote one passage at least in which Mr. Lockyer has associated it with his theory. In this way alone can you justify the assertion in your last editorial note.

Plasma Corona and Dust Corona of the Sun
1994Concerning the structure of the heliomagnetosphere, the 4—sector model with four vertical sector boundaries was proposed by Wilcox et al.(1965). In contrast to this model, the current sheet model(Shulz, 1973), or the two-hemisphere model(Saito, 1975) with the one warped horizontal neutral sheet were proposed (see the review by Saito et al., 198 9a).

Coronal heating--the creation of extremely high temperatures in the outer atmosphere of the sun--represents a difficult phenomenon for solar physicists to explain. A fleet of satellite observatories--such as Yohkoh, SOHO and TRACE--is now providing a wealth of data that may help resolve the mystery. Nakariakov et al.

Total solar eclipses provide a unique view of the faint solar corona, without the bright over-powering emission from the solar disk, enabling us to explore the electron density, temperature, thermodynamics, and related fundamental physics (Habbal et al. 2010a, 2011, 2013).

New facility can recreate Sun's corona
Physics World, 2008Physicists at the GSI lab in Darmstadt, Germany, have successfully tested a new €18m laser that, for the first time, combines a high-energy solid-state neodymium laser beam with a powerful heavy-ion beam. Dubbed the Petawatt High-Energy Laser for Heavy Ion Experiments (PHELIX), it can produce laser pulses with a power of 250 terawatts (250 × 1012 W ...

The magnetic field in the Sun's corona
Science, 2020Solar Physics The solar corona is the outermost layer of the Sun's atmosphere, consisting of hot, diffuse, and highly ionized plasma. The magnetic field in this region is expected to drive many of its physical properties but has been difficult to measure with observations. Yang et al.
