Astrophysical plasma laboratories

Physics World, 1994
Almost all of the material in the Universe is in the form of ionized gas or plasma. The interstellar medium is a low-temperature, low-density plasma whilst the interiors of stars are made of extremely hot and dense plasmas. A variety of different plasma conditions can exist within the same star; the centre of the Sun, for example, is at a temperature ...

Laboratory Astrophysics of Dust

EAS Publications Series, 2011
Infrared spectroscopy is the best astronomical tool for studying the composition of cosmic dust. Thanks to the Herschel satellite, dust properties from the FIR to mm wavelength range will be sampled in different astrophysical environments. In the laboratory, the study of the temperature and structural dependence of FIR absorption of cosmic dust analogs

Our Local Astrophysical Laboratory

Science, 2006
The behavior of the orbiting bodies within Saturn's rings, now being closely observed by the Cassini spacecraft, can inform our understanding of the birth of extrasolar planets.

Laboratory surface astrophysics experiment

Review of Scientific Instruments, 2002
In this article we describe the design and construction of a laboratory astrophysics experiment that recreates the harsh conditions of the Interstellar Medium (ISM) and is used to study the heterogeneous chemistry that occurs there. The Nottingham Surface Astrophysics Experiment is used to determine, empirically, accurately, and usually for the first ...

Laboratory models for astrophysical jets

Journal de Physique IV (Proceedings), 2006
In this paper we will discuss possible links between astrophysical models and observations, with several recent laboratory astrophysics experiments [4-10] performed on laser and pulsed-power facilities which are aimed at tackling some of the issues relevant to jets associated with young stellar objects.

Solar eclipses as an astrophysical laboratory

Nature, 2009
Observations of the Sun during total eclipses have led to major discoveries, such as the existence of helium (from its spectrum), the high temperature of the corona (though the reason for the high temperature remains controversial), and the role of magnetic fields in injecting energy into-and trapping ionized gases within-stellar atmospheres.

Laboratory Astrophysics and Scaling

2009
This chapter is a summary of lectures intended to introduce the concept of scaling to graduate students. Specifically, we address whether astrophysical phenomena may be addressed using ‘scaled’ versions of the same processes in experiments in the laboratory.

Transsonic Instabilities in Laboratory and Astrophysical Plasmas

Physica Scripta, 2004
Waves and instabilities of transsonically rotating axisymmetric plasmas present a highly complex problem that is of interest for two unrelated fields of research, viz. laboratory tokamak confinement for the eventual thermonuclear energy production and the dynamics of a vast number of astrophysical plasmas rotating about compact objects, broadly ...
