PLANET II: A Microlensing and Transit Search for Extrasolar Planets
Penny D. Sackett, M. D. Albrow, J. -P. Beaulieu +16
Due to their extremely small luminosity compared to the stars they orbit, planets outside our own Solar System are extraordinarily difficult to detect directly in optical light. Ca…
Carbon Star Dust from Meteorites
U. G. Jorgensen, A. C. Andersen
Inside carbonaceous chondrite meteorites are tiny dust particles which, when heated, release noble gases with an isotopic composition different from what is found anywhere else in…
Infrared Spectra of Meteoritic SiC Grains
A. C. Andersen, C. Jager, H. Mutschke +5
We present here the first infrared spectra of meteoritic SiC grains. The mid-infrared transmission spectra of meteoritic SiC grains isolated from the Murchison meteorite were measu…
Spectral features of presolar diamonds in the laboratory and in carbon star atmospheres
A. C. Andersen, U. G. Jorgensen, F. M. Nicolaisen +2
Laboratory analyses on fine-grained diamond residues from primitive meteorites have shown that nano-diamonds represent the most abundant form of presolar dust preserved in meteorit…
