Laboratory astrophysics

Journal of Quantitative Spectroscopy and Radiative Transfer, 1962
The development of American astronomy over the last quarter century has been chiefly characterized by the construction of larger and larger telescopes. The size and diversity of those covering the visible spectrum have increased steadily over the period.

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 ...
