Si(Li) X-ray astronomical spectroscopy [PDF]
The general considerations involved in the choice of Si(Li) as a non-dispersive spectrometer for X-ray astronomy are discussed. In particular, its adaptation to HEAO-B is described as an example of the space-borne application of Si(Li ...

FT-IR microanalysis of mineral separates from primitive meteorites: techniques, problems and solutions [PDF]
From the Introduction: We compared several methods of infrared micro spectroscopy using an FT-IR microscope and workbench. This is part of a project to assemble a database of infrared and optical spectra from mineral separates from meteorites, for ...

NAIR: Novel Astronomical Instrumentation through photonic Reformatting [PDF]
The project "Novel Astronomical Instrumentation through photonic Reformatting" is a DFG-funded collaboration to exploit the recognized potential of photonics solutions for a radically new approach to astronomical instrumentation for optical/infrared high precision spectroscopy and high angular resolution imaging.

Determining Redshift via Astronomical Spectroscopy [PDF]
The Doppler effect is a well-known physical phenomenon which results in a change of a wave’s frequency or wavelength due to the motion of its source. Celestial objects in space (stars, galaxies, etc.) also experience a Doppler effect on their emitted ...

Far-red spectroscopy of peculiar stars and the GAIA mission [PDF]
The coming GAIA Cornerstone mission by ESA will provide micro-arcsec astrometry, 10 bands photometry and far-red spectroscopy for a huge number of stars in the Galaxy (10^9). GAIA spectroscopy will cover the range 8480--8740 Ang, which includes the CaII triplet and the head of the Paschen series.

Infrared spectroscopy of extraterrestrial material: comparison with astronomical spectra of dust [PDF]
Infrared spectra of components (CAI, matrix etc.) from type 3 carbonacous chondrites (Allende, Ornans, Vigarano) are compared with infrared spectra from astronomical objects (comets, zodiacal light, circumstellar disks and others)
