The sun as an astrophysical laboratory [PDF]

open access: possibleSpace 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 ...

Recent Progress in Laboratory Astrophysics Achieved with NASA Ames’ COSmIC Facility

Proceedings of the International Astronomical Union, 2017
We describe the characteristics and the capabilities of the laboratory facility, COSmIC, that was developed at NASA Ames to generate, process and analyze interstellar, circumstellar and planetary analogs in the laboratory.

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

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.

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.
