Energy-Dependent Ionization States of Shock-Accelerated Particles in the Solar Corona

, 2000
We examine the range of possible energy dependence of the ionization states of ions that are shock-accelerated from the ambient plasma of the solar corona. If acceleration begins in a region of moderate density, sufficiently low in the corona, ions above

Analyses of the Ancient Chinese Report on the Total Solar Eclipse in 709 BCE: Implications for the Contemporaneous Earth’s Rotation Speed and Solar Cycles

The Astrophysical Journal Letters
Total solar eclipses have occasionally left their footprints on human history for millennia, serving as spot references for the Earth’s rotation speed and the solar cycle variations in the past.

Extended UV corona imaging from the Solar Orbiter: the Ultraviolet and Visible-light Coronagraph (UVC)

, 2001
In the context of the Solar Orbiter mission, the novel concept is presented here of an Ultraviolet and Visible-light Coronagraph (UVC) instrument for the imaging of the full extended corona in UV and visible-light.

Measurements of the Perpendicular Correlation Length of Coronal Alfvénic Waves with DKIST

The Astrophysical Journal
We have measured the perpendicular correlation length L _⊥ of Alfvénic waves in the corona using data from the Daniel K. Inouye Solar Telescope (DKIST) Cryogenic Near Infrared Spectropolarimeter (Cryo-NIRSP) instrument.

Solar Orbiter Neutral Solar Wind Detector

, 2007
Neutral hydrogen atoms, which give rise to the prominent so lar Ly-alpha corona, are closely coup led to the emerging solar-wind plasma. The density ratio of neutral hydrogen to protons is minute, ~10-6; therefore, the neutral atoms are tracers in the ...

Solar orbiter neutral solar-wind detector

, 2006
Neutral hydrogen atoms, which give rise to the prominent solar Ly-? corona, are closely coupled to the emerging solar-wind plasma. The density ratio of neutral hydrogen to protons is minute, ?10-6; therefore, the neutral atoms are tracers in the solar ...

A guide to the solar corona

, 1966
A Guide to the Solar Corona is specifically directed to the space scientist or engineer who is not a specialist in solar physics, but whose work requires a fairly detailed knowledge of the corona.
