astrophysics integrates atomic physics with astrophysics and
plasma physics, aiming at investigations of the atomic structure
of the elements and spectroscopic diagnostics of plasmas.
Basic research is applied to astrophysical and laboratory
plasmas by using spectroscopic techniques. Atomic astrophysics
has been adopted as a research branch within the Faculty of
Sciences. We present our activity under three different domains:
Atomic Spectroscopy, Stellar Spectroscopy, and Industrial
We participate in numerous international and national projects.
For example, during the last decade we have had a lively collaboration
with NASA. Our division is part of Lund Laser Centre.
The research program is since many years continuously supported
by the Swedish Science Council and the Swedish National Space
[The FERRUM Project]
is the information carrier both for atoms and stars. By analyzing
the spectral distribution of the light, the line spectrum, we
can understand the atomic structure and other atomic properties.
The goal of our work is twofold: i) To determine the atomic
structure (energy levels) of atoms and atomic ions experimentally
and ii) to provide experimental data on atomic parameters (wavelengths
and oscillator strengths) of relevance for stellar and plasma
spectroscopy. A modern set of experimental equipment for laboratory
spectroscopy is available.
relationship between atomic and stellar spectroscopy is exemplified
through research activities involving both astrophysical absorption
and emission line spectra. Laboratory data are used to interpret
stellar spectra obtained at both ground-based (e.g. NOT and
ESO) and space-borne (HST and FUSE) observatories. The analysis
of absorption line spectra results in the determination of the
chemical composition of stars. Current projects include the
sun, chemically peculiar (CP) stars, and galactic halo stars.
The analysis of emission line spectra concerns primarily studies
of radiative processes, such as fluorescence and laser activity,
in low-density regions around stars. Current projects include
Eta Carinae and symbiotic stars.
spectroscopy is widely used as a diagnostic tool in various
applications in research and industry. We are participating
in a number of such projects in close collaboration with industrial
partners. The projects are ranging from investigation and modeling
of low-pressure plasmas in fluorescent tubes to instrumentation
for remote diagnostics of metallurgical processes in steel furnaces.
The applications often require dedicated instruments, which
are designed and built in house.
