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

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.

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 ...

The sun as an astrophysical laboratory

Space 2000 Conference and Exposition, 2000
We live next to a star. The variability of that star affects our life hi different ways, as it induces climate changes or subjects spacecraft to the effects of mass ejections. The variability of the Sun provides a unique opportunity to observe processes that occur throughout the universe on scales that are too vast to imagine or to study in a ...

The Heliosphere as an Astrophysical Laboratory for Particle Acceleration

Science, 1989
Particle acceleration is one of the most important topics in plasma astrophysics as well as in cosmic-ray astrophysics. The heliosphere is an ideal astrophysical laboratory, wherein one can observe in situ the elementary mechanisms involved in the particle acceleration processes.

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 ...

The Future of Laboratory Astrophysics

Proceedings of the International Astronomical Union, 2019
AbstractA Round Table discussion on the future of Laboratory Astrophysics and the role of IAU Commission B5 was held on the fourth day of the conference to discuss how the IAU Laboratory Astrophysics Commission (B5) can best support the astronomy community and help promote laboratory astrophysics.

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.

Magnetohydrodynamic waves in laboratory and astrophysical plasmas

AIP Conference Proceedings, 2000
The study of magnetohydrodynamic waves and instabilities of both laboratory and astrophysical plasmas has been conducted for many years starting from the assumption of static equilibrium. Recently, there is an outburst of interest for plasma states where this assumption is violated.
