Understanding our future through Open Access research about our past...

Strathprints makes available scholarly Open Access content by researchers in the Centre for the Social History of Health & Healthcare (CSHHH), based within the School of Humanities, and considered Scotland's leading centre for the history of health and medicine.

Research at CSHHH explores the modern world since 1800 in locations as diverse as the UK, Asia, Africa, North America, and Europe. Areas of specialism include contraception and sexuality; family health and medical services; occupational health and medicine; disability; the history of psychiatry; conflict and warfare; and, drugs, pharmaceuticals and intoxicants.

Abstract

A comparison is made between one of the processes leading to cometary X-ray emission and X-rays from supernova remnants. We demonstrate that the X-ray emission in both comet and supernova is bremsstrahlung and line radiation created by energetic electrons accelerated by plasma turbulence. We further demonstrate that the most likely source of plasma turbulence is produced by counterstreaming ion populations which result from the mass loading effect or from an anisotropic distribution produced by reflecting ions from a collisionless shock. The instability that gives rise to the plasma turbulence is the modified two-stream instability of counterstreaming ions. A similar instability arises in laser-plasma interactions that have self-generating magnetic fields and flowing ions.
