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.

Laboratory astrophysics in the extreme ultraviolet

Canadian Journal of Physics, 2008
Electron beam ion traps are uniquely well suited for laboratory astrophysics because they can produce nearly any charge state of any element in a collisionally excited plasma that is comparable in density and temperature to many astronomical sources.

Laboratory and Computational Studies of Interstellar Ices

Annual Review of Astronomy and Astrophysics
Ice mantles play a crucial role in shaping the astrochemical inventory of molecules during star and planet formation. Small-scale molecular processes have a profound impact on large-scale astronomical evolution.

Laboratory X-Ray Astrophysics [PDF]

Annual Review of Astronomy and Astrophysics, 2003
▪ Abstract  Targeted laboratory astrophysics measurements are being conducted to address the needs of X-ray astronomy. The measurements are producing large sets of reliable atomic data, which include ionization and recombination cross sections for charge balance calculations, as well as line lists, excitation cross sections, and dielectronic ...

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 ...

Simulation of Astrophysical Processes in the Laboratory

Nature, 1957
A PLASMA gun (or plasma source) has been developed which can project plasmoids1 (plasma-magnetic entities) across a magnetic field (in a vacuum) at speeds up to 107 cm./sec. A Taylor-instability jet2 produced in a plasma supported against gravity by magnetic field may thus be simulated and studied in the laboratory.

Laboratory astrophysics with shock tubes

2022
Astrophysical shocks participate to the chemical evolution of the interstellar medium. These violent events strongly alter dust grains and lead to the release of new molecular species in the gas phase. Only a few studies on the shock processing of cosmic analogues have been conducted so far.We explored in the laboratory the destruction of dust ...
