The Corona of the Sun as a Star

AIP Conference Proceedings, 2006
We study the physics of the solar corona as a whole, i.e. of the Sun as a Star, in order to understand its global features and to provide a template for stellar coronae.

Corona and XUV emission modelling of the Sun and Sun-like stars [PDF]

Astronomy & Astrophysics, 2021
The X-ray and extreme-ultraviolet (EUV) emissions from low-mass stars significantly affect the evolution of the planetary atmosphere. However, it is observationally difficult to constrain the stellar high-energy emission because of the strong interstellar extinction of EUV photons.

POLAR investigation of the Sun—POLARIS [PDF]

, 2008
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the Sun with an inclination of 75° with respect to solar equator.

MHD turbulence and heating of the open field-line solar corona [PDF]

, 2003
This paper discusses the possibility that heating of the solar corona in open field-line regions emanating from coronal holes is due to a nonlinear cascade, driven by low-frequency or quasi-static magnetohydrodynamic fluctuations.

Small scale energy release driven by supergranular flows on the quiet Sun [PDF]

, 2007
In this article we present data and modelling for the quiet Sun that strongly suggest a ubiquitous small-scale atmospheric heating mechanism that is driven solely by converging supergranular flows. A possible energy source for such events is the power

Near-Sun observations of an F-corona decrease and K-corona fine structure [PDF]

The Sun's Corona, 1889 [PDF]

Nature, 1889
A GENERAL statement of the successes of the Western Eclipse Expeditions on January 1 has already appeared in NATURE. More photographs of the corona were taken than ever before—many of them indifferent and worthless, but an unusually large number of great excellence. The best that I have so far seen were taken with 5-inch telescopes, by Mr. W.
