abstract

The UK scientific community has access to outstanding astronomical
observing facilities, enabling it to make observations at all
wavelengths from radio to X-ray. The interpretation of these can often
only be achieved by a quantitative comparison between an observed
spectrum and a theoretical model. Sophisticated calculations of
atomic, chemical and radiative processes in the emitting plasma, as
well as self-consistent models of the objects themselves, can lead to
the inferrence of fundamental properties of the emitter (e.g. kinetic
temperature, electron density, chemical composition, geometry,
dynamics and stratification). These calculations depend on realistic
algorithms, large quantities of atomic and molecular data, and
substantial computational resources. CCP7 is concerned with providing
the UK astronomical community with access to suitable resources,
particularly in the domain of stellar atmospheres and the interstellar
medium. It pursues specific research objectives in a number of
selected areas and plays a key role in providing a communication
channel between astronomers, physicists and chemists with common
interests.
