81. Time dependence of heavy ion ratios in solar events

Author: Peter Zelina and Silvia Dalla (University of Central Lancashire).

<< previous nuggetnext nugget >>

Introduction

Violent eruptions at the Sun, solar flares and coronal mass ejections, occur with frequency correlated with the 11-year solar cycle. They are sometimes accompanied by energetic particles up to GeV energies observed in situ in the interplanetary medium, by particle instruments onboard spacecraft.… continue to the full article

Introduction

Ground based white light images taken during total solar eclipses have many unique advantages, particularly their very high dynamic range spanning tens of solar radii starting from the solar surface.… continue to the full article

Introduction

During a solar flare, rare infrared (IR) continuum observations show strong brightenings in the chromosphere, co-spatial and co-temporal with flare hard X-ray footpoints [1].… continue to the full article

75. Probing the corona through infrared observations

Author: Richard Morton at  Northumbria University.

<< previous nuggetnext nugget >>

Introduction

The Sun’s corona has intrigued scientists since its discovery around the start of the last century. Over the years, understanding how the coronal plasma is heated to temperatures in excess of 106 Kelvin and the mechanisms which accelerate some of this plasma as it flows out into the heliosphere, forming the solar wind, have proved stubborn problems.… continue to the full article

72. Particle dynamics in a non-flaring solar active region model

Authors: James Threlfall, Thomas Neukirch and Clare E. Parnell at the University of St Andrews; Philippe-Andre Bourdin at IWF, Austrian Academy of Sciences.

<< previous nuggetnext nugget >>

Introduction

Understanding the behaviour of charged particles in dynamical solar processes (particularly those underpinned by magnetic reconnection) is fundamentally important for plasma behaviour in general, not least to uncover how vast quantities of electrons and protons are accelerated to high energies during solar flares, micro-flares and even nano-flares.… continue to the full article
